And when K is a neutral ligand m is increased by one for each neutral K ligand? N is the number of the R 'groups attached to the electron donor heterogeneous atom D? Whereby when D is selected from group 15 of the periodic table ca of the elements n is 2? and when D is selected from group 16 of the periodic table of elements n is 1? q? s and s are the number of groups (-Rt-DR'n) and groups
(Ar-Rt_) joined to group Y? respectively? in dande q + s is an integer not less than 1. and t is the number of groups R that connect each of (i) the groups Y and Ar and < ii > the groups Y and DRr "? where t is independently selected as 0 or 1. These and other objects? characteristics and advantages of the present invention will become apparent from the following detailed description when taken in conjunction with the accompanying drawings that illustrate? as an example? the principles of the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying drawings illustrate the present invention. In said drawings? Fig. 1 is a schematic view of a cationic active site of a trivalent catalyst complex according to one embodiment of the present invention? and Figure 2 is a schematic view of a neutral active site of a trivalent catalyst complex of a dianionic ligand of a conventional catalyst complex according to WO-A-93 19104.
DESCRIPTION OF THE PREFERRED MODALITIES
Next, several components (groups) of the transition metal complex are described in more detail.
(a) The transition metal (M) The transition metal in the complex is selected from groups 4-6 of the periodic table of the elements. As mentioned here? all references to the periodic table of the elements refer to the version established in the new? UPAC notation found inside the cover of Handbook of Chemistry and Physics? 70th edition? 1989/1990? whose full description is incorporated herein by way of reference. In a very preferable way? the transition metal is selected from group 4 of the periodic table of the elements? and very preferably it is titanium (Ti). The transition metal is present in reduced form in the complex? which means that the transition metal is in a reduced oxidation state. As mentioned here? "Reduced oxidation state" means an oxidation state that is greater than zero but less than the highest possible oxidation state of the metal (for example, the reduced oxidation state is at most M ^ + for a metal, transitional from group 4? at most? ** for a transition metal from group 5 and at most Ms' * "for a transition metal from group 6).
(b) The ligand X The ligand X in a multidentate monoanionic ligand represented by the formula? (Ar ~ Rt-) BY (-Rt-DR'r?) El. As mentioned here? a multidentate monoanionic ligand is linked with a covalent bond to the reduced transition metal (I) at a site (the anionic site Y) and is either linked to < i) with a coordinated junction to the transition metal at a different site (bidentate) or (ii) with a plurality of coordinated junctions at several other sites (tridentate, tetradentate, etc.). Can this coordinated union take place? for example? by means of the heterogeneous atom D or group (s) Ar. Examples of tri-toothed ionic ionic onoe include? without limitation? Y-Rt ~ DRr, _L-R * -DRr "and Y (~ R-D") 2.
Nevertheless? it is noted that the heterogeneous atom (s) or aryl substituent (s) can be present on the group Y without coordinating the reduced transition metal! ? provided that at least one coordinated linkage is formed between an electron donating group D or an electron donating group Ar and the reduced transition metal M.R represents a linking or bridging group between the
DRr "and Y? and / or between the aryl group (Ar) electron donor and
Y. Since R is optional? "t" can be zero. The group R is described in more detail later in paragraph (d).
< c) The group Y The group Y of the multidentate monoanionic ligand (X) is preferably a cyclopentadienyl group? amido (-NRr-> or phosphido (-PR'-). Most preferably, the group Y is a cyclopentadienyl ligand (Cp group). As referred to herein, the term "cyclopentadienyl group" encompasses substituted cyclopentadienyl groups such as indenyl? fluorenyl and benzoindenyl groups and other cyclic aromatic palms containing at least one 5-membered dienyl ring, provided that at least one of the substituents of the Cp group is a group
Rt ~ DRrn or group R ^ -Ar which replaces one of the hydrogens attached to the five-member ring of the Cp group by means of an exocyclic substitution. Examplee of a multidentate monoanionic ligand with a Cp group such as the group Y (or ligand) include the following
, 15 (with the substituent (-R-t-DR '") or (Ai - Rt) on the ring) s
R-D R-Ar
2? The group Y can also be a heterogeneous cyclopentadienyl group. As referenced here? A heterogeneous cyclopentadienyl group means a heterogeneous ligand derived from a cyclopentadienyl group? but in which at least one of the atoms that define the five-membered ring structure of the cyclopentadienyl is replaced with a heterogeneous atom by an endocyclic reformation. The heterogeneous Cp group also includes at least one Rt-DR '"group or Rt-Ar group which replaces one of the hydrogens attached to the five-member ring of the Cp group by means of an exocyclic substitution. As with the group Cp? as referenced here? the heterogeneous Cp group includes groups, indenyl? fluorenyl and benzoindeni what? and other polycyclic aromatics containing at least one 5-membered dienyl ring? provided that at least one of the substituents of the heterogeneous Cp group is an Rt-DR '"group or Rt-Ar group which replaces one of the hydrogens attached to the five-membered ring of the heterogeneous Cp group by means of an exocyclic substitution. The heterogeneous atom can be selected from. group
14? 15 or 16 of the periodic table of the elements. If there is more than one heterogeneous atom present in the five-membered ring? These heterogeneous atoms can be either the same or different from each other. In a very preferable way? the heterogeneous atom (s) is selected from group 15? and even more preferable? the selected heterogeneous atom (s) (s> is / are phosphorus.) By way of illustration and without limitation, the heterogeneous ligands representative of the group X can be carried out in accordance with the present invention are heterogeneous cyclopentadienyl groups having the following structures en in which the heterogeneous cyclopentadienyl contains a phosphorus atom (i.e. the heterogeneous atom) substituted in the five membered ring?
R-DR
It is noted that? usually? the group of the transition metal M is attached to the group Cp by means of a bond l5. The other exacyclic substituents R7 (shown in formula (III)) on the ring of the heterogeneous Cp group can be of the same type as those present on the Cp group? as represented in formula (II). As in the formula (H)? at least one of the exocyclic substituents on the five-membered ring of the heterogeneous cyclopentadienyl group of the formula (III) is the group Rt-DR '"or the group R ^ -Ar. The numbering of the substitution sites of the indenyl group is in general and in the present description based on the IUPAC nomenclature of Organic Chemistry 1979? rule A 21.1. The numeration of the substitute sites for indene shows below. This numbering is analogous to an indeni lo group; Indeno
The group Y can also be an amido group (-R'-) or a group fasfido (-PR'-). In these alternative modalities? the group Y contains nitrogen (N) or phosphorus (P) and is covalently bound to the transition metal ti? as well as the group R
(optional) of the substituent (-Rt-DR '") or (Ar-Rt-).
(d) The R group The R group is optional? so that he may be absent from group X. When group R is aueente? the group DR '"or Ar is directly attached to the group Y (ie the group DR'" or Ar is directly attached to the group Cp? amide to phosphide). The presence in the absence of a group R between each of the groups DR '"and / or groups Ar is independent. When at least one of the R groups is present? each of the group R constitutes the connecting junction between? On the one hand the group Y? and on the other hand the group DR '"or the group Ar. The presence and size of the group R determines the accessibility of the transition metal M in relation to the group DR ', _, or Ar? which gives the desired intramolecular coordination. If the group R (or bridge) is too short or absent? the donor may not coordinate well due to ring tension. The R groups are each independently selected? and generally can be? for example? a hydrocarbon group with 1 ~ 20 carbon atoms (eg, alkylidene, arylidene, aryl, ideno, etc.). Specific examples of said R groups include? without limitation? methylene? Ethylene? propylene? butylene? phenylene? whether or not with a substituted side chain. Preferably? Does the group R have the following structure?
(-CR1 (IV)
where p = 1-4. The groups of the formula (IV) can each be independently selected? and they may be the same as the groups R 'defined below in paragraph (g). In addition to carbon? the main chain of the R group may also contain eilium or germanium. Examples of such R groups are? dialqui Isi 1 i le or (-SiR'j, -)? dialqui Igermi to (- GeR'j, -)? tetra-alkylsilylene (-SiR '- »- SiR' s-) or tetraalkylsilyethylene (-SiR'jgCR '-, -)« The alkyl groups in said group preferably have 1-4 carbon atoms and most preferably are a methyl or ethyl group, (e) The group '"This donor group consists of a heterogeneous electron donor D selected from group 15 or 16 of the periodic table of the elements? and one or more substituents R 'linked to D. The number < n) of groups R 'is determined by the nature of the heterogeneous atom D? while n is 2 if D is selected from group 15 and n being 1 if D is selected from group 16. Substituents R 'linked to D may each be independently selected and may be the same as the R' groups defined below in paragraph (g)? with the exception that the substituent R 'linked to D can not be hydrogen. The heterogeneous atom D is preferably selected from the group consisting of nitrogen < N)? oxygen (0)? phosphorus (P) and sulfur (s)? very preferably? the heterogeneous atom is nitrogen (N). Preferably? he. group R 'is an alkyl group? most preferably an n-alkyl group having 1-20 carbon atoms and most preferably an n-alkyl having 1-8 carbon atoms. It is also possible that two groups Rr in the group DR '"are connected to each other to form a ring-shaped structure (whereby the group DR' ^ can be for example a pyrrolidinyl group). The group DR '"can form coordinated junctions with the transition metal M.
(f) The Ar Group The selected electron donor group can also be an aryl group? Í ^ R '^)? such as phenyl? tolyl? xylyl? mesitila? cumenil? tetra eti Ifeni what? peta eti Ifeni la? a polycyclic group such as triphenylmethane? etc. Nevertheless? the electron donor group D of the formula (I) can not be a substituted Cp group such as an indenyl group? benzoindeni lo or fluorenyl. The coordination of this group Ar in relation to the transition metal li can vary from * 1 to r] 6.
(g) The group R 'The R' groups can each be separately hydrogen or a hydrocarbon radical with 1-20 carbon atoms (e.g.? alkyl? aryl? arylalkyl and the like as shown in table 1) ) «Examples of alkyl groups are methyl? ethyl? propyl? butyl? Hexyl and decyl. Example of aryl group phenyl mesitila? tolyl and cumenyl. Examples of arylalkyl groups are benzyl? pentameti Ibencilo? xylyl? styryl and trityl. Example of other R 'groups are halides? such as chloride? bromide to fluoride and iodide? metaxi? ethoxy and phenoxy. Similarly? two adjacent hydrocarbon radicals of group Y can be connected to each other to define a ring system? therefore group Y can be an indenyl group? a fluorenyl group or a benzaindenyl group lo. The indenyl? Fluorenyl and / or benzoindeni may contain one or more R 'co or substituent groups. Rt can also be a substituent that instead of? or in addition to the carbon and / or hydrogen may comprise one or more heterogeneous atoms of groups 14-16 of the periodic table of the elements. In this way? a substituent can it be? for example? a group that contains Si? such as Si (CH3) 3.
(h) Group L The transition metal complex contains two monoanionic L ligands attached to the transition metal M.
Examples of the L group ligands? which can be identical or different? include? without limitation? the following? a hydrogen atom? a halogen atom? an alkyl group? aryl or arylalkyl? an alkoxy or aryloxy group? a group that understands a heterogeneous atom selected from group 15 or 16 of the periodic table of the elements? including? for example? (i) a sulfur compound? such as sulfite? sulfate? thiol? sulfonate and tisalkyl and (ii) a phosphorus compound? such as phosphate and phosphata. The doe L groups can also be connected to each other to form a biannual dianionic ring system. These and other ligands can be tested to verify their suitability by means of simple experiments by a person skilled in the art.
Preferably? L is a halide and / or an alkyl or aryl group? very preferably? L is a Cl group and / or an alkyl group of Cj ^ -C ^. or a benci la group. Nevertheless? the group L can not be a group Cp? amido or phosphide. In other s? L can not be one of the groups Y.
(i) The ligand The ligand K is a neutral or anionic group attached to the transition metal M. The group is a neutral or anionic ligand bound to li .. When K is a neutral ligand K can it be absent? But when is monoanionic K? the following is for
m = for M3 * m = 1 for M ** = 2 for Ms * On the other hand? the neutral K ligands? which by definition are not anionic? na are subject to the same rule. Thus? for each neutral K ligand? the value of (ie, the number of total ligands) is greater than the value mentioned above for a complex having all the anoanilic K ligands. The ligand can be a ligand as described above for the L group or a Cp group (-CSR'B). an amido group
(-NR'jj or a phosphide group (-PR '.-.) .The group I. can also be a neutral ligand such as an ether? An amine? A phosphine? A thioether? Among others.
If two K groups are present? the two groups can be connected to each other by means of a group R to form a bidentate ring system. As can also be seen from the formula (I)? group X of the complex contains a group Y to which are linked one or more donor groups (the group (s) Ar and / or croup (s) DR '^) by means of? optionally? a group R. The number of donor groups linked to the group Y is at least one and at most the number of sites of suetitución preeentes on a group Y. With reference? as an example? to the structure according to formula (II)? at least one substitution site on a group Cp is made by means of a group Rt-r or by means of a group Rt-DR '"(in which case q + s = 1). If all the groups Rr of the formula (II) were Rt-Ar? groups R-t-DR '"or any combination thereof? the value of (q + s) would be 5. A preferred embodiment of the catalyst composition according to the present invention encamises a transition metal complex in which a bi-dentate / monoanionic ligand is present? and in which the reduced transition metal has been selected from group 4 of the periodic table of the elements and has an oxidation state of +3. In this case? the catalyst composition according to the invention comprises a transition metal complex represented by the formula (V)
X i M_III) - L. (V) I
wherein the symbols have the same meaning as that described above for formula (I) and where li (III) is a transition metal selected from group 4 of the periodic table of the elements and is in oxidation state 3+. Said transition metal complex has no anionic ligands K (for an anionic K = 0 in case of li3 *). It should be noted that WO-A-93/19104 describes transition metal complexes in which a transition metal of group 4 is present in a reduced oxidation state (3+). The complexes described in WO-A-3/19104 have the general formula?
Cp ^ (ZY) b) ILI (VI)
The group Y in this formula (VI) is a heterogeneous atom? such as phosphorus? oxygen? sulfur or nitrogen covalently bonded to the transition metal M (see page 2 of WO-A-93/19104). This means that the group Cpra? (2Y) fcJ is dianofic in nature and has the anionic charges residing above the groups Cp and Y. Accordingly? the group Cp ^ iZY ^ of formula (VI) contains two covalent bonds; the first being between the ring of 5 members of group Cp and the transition metal M? and the second being between the group Y and the transition metal. By contrast? the group X in the complex according to the present invention is monoanionic in nature? so that a covalent bond between the group Y (eg, the group Cp) and the transition metal is present? and a coordinate link may be present between the transition metal M and one or more of the groups (Ar-Rt-) and (-Rt-D '"). This changes the nature of the transition metal complex and consequently the nature of the catalyst that is active in the polymerization. As referenced here? A coordinated union is a union (.v .gr ^ r H3.N-BH3) that when it is broken? produces either <i) two species with no net charge and no unpaired electrons (eg,? H3N? and BH-3) or (ii) doe species with net charge and with unpaired electrons (eg.? H3N- * y BH ^ -). On the other hand? Was it referred to here? A covalent bond is a union (eg,? CH3-CH3) that when broken produces either (i) two species with no net charge and with unpaired electrons (eg.? CH3- and CH3-) or ( ii) two species with net charges and no unpaired electrons (v «gr«? CH3 * and CH3? - ")» A description of coordinated and covalent bonds is established in Haaland et al. (Angew. Chem Int. Ed. Eng Vol. 28? 1989? P 992), the complete description of which is hereby incorporated by reference.
IO
Is the following explanation proposed? although it is clarified that the present invention is not limited in any way to this theory. Referring now more particularly to Figure 2? The transition metal complexes described in WO-A-93/19104 are ionic after interaction with the cocatalyst. Nevertheless? the transition metal complex according to WO-A-93/19104 which is active in the polymerization contains a complete neutral charge (based on the assumption that the transition metal complex of polymerization comprises a transition metal M ( III) - a dianionic ligand and a growing monaanionic palmeric chain (POL)). By contrast? as shown in figure 1? the active transition metal complex in the polymerization of the catalyst composition according to the present invention is cationic in nature (assuming that the polymerization transition metal complex - based on the structure of the formula (V) - comprises a transition metal M (III)? a bidentate manaanio ligand and a growing monoanionic polymer (POL)). The complexes of transition metal in which the transition metal is in a state of reduced oxidation? but who have the following structure?
Cp M.III. L. (vri) are generally not active in co-polymerization reactions. Is it precisely the presence? in the transition metal complex of the present invention? of the group DR ', or Ar (the donor)? optionally linked to the group Y by means of the group R. which gives a stable and suitable transition metal complex for polimerization. Said intramolecular donor will be preferred over an external donor (intermolecular) taking into account the fact that the former shows a more stable and stronger coordination with the transition metal complex. It will be appreciated that the catalyst system can also be formed in situ if the components thereof are added directly to the polymerization reactor system? and if a salvente or diluent is used? including liquid monomer? in said polymerization reactor. The catalyst composition of the present invention also contains a co-catalyst. For example? the co-catalyst may be an organometallic compound. The metal of the organometallic compound can be selected from group 1? 2? 12 or 13 of the periodic table of the elements »Suitable metals include? for example and without limitation? sodium? lithium? zinc? Agnesium and aluminum? aluminum is preferred. At least one hydrocarbon radical is attached directly to the metal to provide a carbon-etal bond. The hydrocarbon group used in said compounds preferably contains 1-30? most preferably 1-10 carbon atoms. Examples of suitable compounds include? without limitation? amilo-sadio? Butyl lithium? diethyl zinc? buti l-magnesium chloride and dibuti Imagnesium. Is preference given to organoalumium compounds? including? for example and without limitation? the following? trialqui lalu inia compounds? such as triethylaluminum and tri-isabuti lauminum? hydrides of alqui laluminia? such as di-isobutyl hydride laluminum? Alkylalkoxy organoaluminum compounds? and organoaluminum compounds that contain halogen? such diethylaluminum chloride bed? di-isobu and aluminum chloride and sesquiclorura of etiumuminia. Preferably? linear or cyclic aluminoxanes are selected as the organoalu inium compound. In addition to? or as an alternative for organometallic compounds such as co-catalyst? the catalyst composition of the present invention can include a compound that contains or that produces in a reaction with the transition metal of the present invention? an anion not coordinated or poor coordination coordination. Such compounds have been described, for example, in EP-A-426? 637? whose full description is incorporated herein by way of reference. This anion is united in a way unstable enough to be replaced by an unsaturated monomer during the codend! imerization. Said compounds are also mentioned in EP-A-277? 003 and EP-A-277,004? whose full descriptions are incorporated herein by way of reference. Said compound preferably contains a triarylborane or a tetraarylborate or an aluminum equivalent thereof. Examples of suitable co-catalyst compounds include? without limitation? the following? - tetrakis (pentafluoropheni 1) borate dimeti lani 1 inio CC -.ßN_CH3_ßH3 * Z B iC ^ F ^ ^ l-í - bis <; 7? 8-dicarbaundecaborate) -cobalt tato < I I I) of di-ethylanilinium-tetrafeni-Iborate of tri (n-butyl) ammonium? - tetrakis (pentafluoropheni 1) tri-phene-1-carbenium borate? - Tetrafeni dimethyl anilineium Iborate? - tris (pentafl uarof ni 1) orano? and - tetrakis (eg af1 uorof i1) borate. If the non-coordinating anion or deficient coordination mentioned above is used? it is preferable that the transition metal complex be alkylated (ie, that the L group is an alkyl group). As described for example in EP-A-500? 944? whose full description is incorporated herein by way of reference? can the reaction product of a halogenated transition metal complex and an organometallic compound also be used? such as, for example, triethylaluminium (TEA). The molar ratio of the co-catalyze in relation to the transition metal complex? in case an organometallic compound is selected as the co-catalyst? is usually on a scale of about 1? 1 to about 10? 000? 1? and preferably it is on a scale of about 1? 1 to about 2? 500? 1. If a compound containing or producing a noncoordinating anion or poor coordination is selected as the co-catalyst? the molar ratio is usually on a scale of about 1? 100 to about 1? 000? 1? and preferably on a scale of about 1? 2 to about 250? 1. How could a person skilled in the art notice? the transition metal complex? as well as the co-catalyst may be present in the catalyst composition as a single component or as a mixture of component parts. For example? can a mixture be desired when there is a need to influence the molecular properties of the polymer? such as molecular weight and in particular molecular weight distribution. The inert support component can be any finely divided porous support? including? but not limited to? MgClj ,? zeolites? mineral clays? Inorganic oxides such as talc? silica? alumina? s lice-alumina? Inorganic hydroxides? phosphates? sulfates? etc.? or resinous materials such as polyolefins? including polystyrene? or mixtures thereof. Can these vehicles be used as such or modified? for example by silanes and / or aluminum alkyls and / or aluminoxane compounds? etc. The transition metal complex to the ca-catalyst is supported on a vehicle. It is also possible that both the transition metal complex and the co-catalyst are supported on a vehicle. The carrier material for the transition metal complex and for the co-catalyst may be the same material or a different material. It is also possible to support the transition metal complex and the co-catalyst on the same vehicle. The supported catalyst systems of the present invention can be prepared as separate compounds? which can be used as such in polymerization reactions? or the supported catalyst systems can be formed in situ just before a polymerization reaction is initiated. The supported catalyst systems of the invention can be prepared by various methods. The transition metal complex of group 4-6 and the aluminoxane component / can be mixed before the addition of the soup material? or the mixture can be added to the support material. The mixture can be prepared in a conventional solution in an alkane or aromatic solvent nor in liquid form. These solvents include? but are not limited to? linear or branched alkanes such as pentane? hexane »heptane» pentamethyl-heptane? isobutane and isopene and aromatic solvents such as toluene. The solvent is preferably also suitable for use with a poly erization diluent for the liquid phase polymerization of an olefin onomer. As an alternative? the inau alu can they be placed on the support material followed by the addition of the transition metal complex? or in an inverea way? the transition metal complex can be applied to the support material followed by the addition of the alu i oxanoe. Can aluminoxanes be used as commercially available? or can they be generated in situ on the solid support? for example? by adding a trialqui laluminium compound to a hydrated support? for example? with the addition of tetramethi aluminum to a silica moistened to dehydrated. The supported catalyst can be pre-mixed. Further? third components can be added at any stage of the preparation of the supported catalyst. The third components can be defined as compounds containing acidic or Lewis base functionalities exemplified but not limited by such compounds as N? N-dimethanol? tetraetoxisi tin? phenyl trietoxisi tin? bis-ter-but i Ihi droxi tol ueno (BHT) and ei ires. It has been discovered that the transition metal components in which the metal is titanium impart beneficial properties to a catalyst system? which is unexpected in view of what is known about the properties of the cyclopentadienyl titanium compounds that are ca-catalyzed by aluminoxanoe. While titanocenoe in their soluble form are generally unstable in the presence of aluminum alkyls? The metal components of this invention generally exhibit greater stability (ie, longer catalyst life)? resulting in higher catalyst activity rates (expressed as kg of polymer produced per g of Ti per hour). A higher tx-olefin comonomer incorporation at a high molecular weight are also surprisingly advantageous features of the catalyst systems according to the invention ("molecular weight capacity of the comonomers"). In summary? the supported catalyst systems of the invention comprise a reduced transition metal complex? a vehicle and optionally one or more organoaluminum compounds and / or a compound that contains or produces a non-co-ordinating anion or deficient coordination in a reaction with the transition metal composite. E the procedure according to the invention? The polymerization of tx-olefin monomers is carried out using a supported catalyst system as described above. In particular? the manomer (s) of "-olefin is / are appropriately selected from the group comprising ethene? propene »butene? Pentene? heptena? hexene? octene and styrene (substituted or unsubstituted). Mixtures of these compounds can also be used. In a very preferable way? ethene and / or propene are used as the OI-olefin. Does the use of said olefins result in the formation of meroe polypropylene (semi) crietalinoe homo- and copol? high as well as low density (HDPE? LDPE? LLDPE? et.)? and homo- and copolymer polypropylenes (PP and EtiPP (polypropylene modified with elastomer)). Ethylene is very preferably used as the α-olefin in combination with butene? hexene or octene. The monomers necessary for said products and the methods to be used are known to those skilled in the art. The process according to the invention is also suitable for the preparation of amorphous or rubber-like copal or ethereal or other olefin-based copal. It is preferably used prapßno as the other oc-ale ina? by which EPM rubber is formed. It is also possible to use other dienes that are not ether and other "-olefins". in such a way that a so-called EADM polymer (terpolymer of ethylene-olefin-diene) is formed? in particular EPDM (ethene-propene-diene rubber). The polymerization of the α-olefin monomer (s) can be carried out in a known manner. in the gas phase? as well as in a liquid reaction medium. Both the polymerization of solution and suspension are adequate for use in a liquid reaction medium. The supported catalyst systems according to the invention mainly operate in gas phase and suspension processes. The amount of transition metal that will be used is generally such that its concentration in the dispersing agent is between about 10_ß and 10-3 mol / l? preferably between about 10 ~ "f 'and 10 ~ * mol / L. The invention will be described hereinafter with reference to polymerizations of" -olefins known per se which are representative of the polymerization referred to. In the present description, for the preparation of other polymers on the basis of "-alphafin monomers, the reader will be referred to the multitude of publications in this material." The process of the present invention can be carried out as a phase polymerization. of gas (eg in a fluidized bed reactor) as a suspension polymerization as a solid Jase powder polymerization or as a so-called intermittent polymerization process using excess alefinic monomer as the reaction medium. can properly use dispersion agents for polimerization which can be chosen from (but not limited to) straight or branched aliphatic hydrocarbons? ee as butanes? pentanes? hexanes? heptanes? pentamet i Iheptana or fractions of mineral oil such as light or regular oil? naphtha? kerosene or gas oil. Similar fluorinated or liquid hydrocarbons are also suitable for this purpose. Can aromatic hydrocarbons also be used? for example benzene and toluene? but due to the considerations of costro and security »it is preferable not to use said solvents for the production on a technical scale. In polymerization procedures on a technical scale? Is it preferred to use inexpensive aliphatic hydrocarbons or mixtures thereof as solvents? talee like those marketed by the petrochemical industry. If an aliphatic hydrocarbon is used as a solvent? can the solvent also contain minor amounts of an aromatic hydrocarbon? for example toluene. Of eeta way? if for example methyl aluminoxane (MAO) co or co-catalyst is used? toluene can be used as a solvent for the MAO to supply the MAO in dissolved form to the polymerization reactor. Drying or purification of solvents is desirable if such solvents are used? this can be achieved using procedures known to those skilled in the art. In the procedure of the invention? the catalyst and co-catalyst are used in a catalytically effective amount? that is to say? any amount that successfully results in the formation of the polymer. Said amounts can be easily determined by routine experimentation by the person skilled in the art. It will be appreciated that the catalyst system can also be formed in situ if the components thereof are added directly to the polymerization reactor system? and a solvent or diluent is used? including liquid monomer? in the polymerization reactor. If you were going to use a solution or global policy? Is it necessary to carry it out at temperatures well above the melting point of the polymer that will be produced? typically? but not limited to? Are temperatures between 120 ° C and 260 ° C_ According to a preferred embodiment of the invention? the process is carried out under suspension or gas phase polymerization conditions which typically take place at temperatures well below the melting temperature of the polymer to be produced? typically? but not limited to? temperatures below 105 ° C. The polymer resulting from the polymerization can be made by methods known to the person skilled in the art. In general? the catalyst is deactivated at the same point during polymer processing. Disabling is also carried out in a way known per se? v.gr. by means of water or an alcohol. The removal of catalyst residues can normally be omitted because the amount of catalyst in the polymer? in particular the content of halogen and transition metal? is very low when using the catalyst system according to the invention. The polymerization can be carried out at atmospheric pressure? at subatmospheric pressure or at high pressure up to 500 MPa? continuously or discontinuously. Preferably, the polymerization is carried out at pressures between
O.Ol and 500 MPa? very preferred between 0.01 and IO MPa? in particular between 5 and 30 bar (. - 0.5-3 MPa). Higher pressures of up to about 500 MPa can be applied. In a procedure of such high pressure? the process according to the present invention can also be used with good results.
