Definitions
- the invention relates to a stabilized peroxydicarbonate preparation and its use in the polymerization or copolymerization of ethylenically unsaturated compounds.
- Peroxydicarbonates have the general formula RO-CO-O-O-CO-OR, in which R represents organic radicals, generally alkyl, alkylene and aryl radicals. They are particularly suitable for initiating polymerization reactions, since they decompose into radicals by thermolysis even at relatively low temperatures. These peroxydicarbonates are preferably used for the polymerization of vinyl halides, in particular vinyl chloride, and can be used in an aqueous medium, for example as an emulsion, in solution or in suspension polymerization. However, their low disintegration temperature, which is advantageous for use in the context of polymerizations, causes problems in storage, shipping and handling.
- compositions of the peroxide and the stabilizer compound have been proposed for this purpose, but in practice temperatures of a maximum of -20 ° C. have to be maintained.
- Phenolic antioxidants (US Pat. No. 4,552,682), hydroperoxides (US Pat. No. 5,155, 192), unsaturated nitriles or 1,3 alkenines (US Pat. No. 5,541,151) are used as stabilizer compounds in such compositions. ? -Dicarbonyl compounds (US 5,714,626), phosphoromolybdic acids (US 5,719,304) or oximes (US 5,892,090) are used.
- these stabilized compositions which were developed over a period of more than 15 years, still leave something to be desired, particularly as regards stabilization without diluents and desensitizers and the low temperatures to be observed for storage stability.
- the known stabilizer additives are sometimes toxic or have a negative effect on the color stability of the polymer produced with them.
- the invention is therefore based on the object of providing a stabilized peroxydicarbonate preparation which can be stored even at temperatures higher than -20 ° C., even if the peroxide is not in dissolved form but as a pure product.
- a stabilized peroxydicarbonate preparation which is characterized in that it essentially consists of a peroxydicarbonate and at least one alpha-unsaturated ketone of the general formula (I)
- R 4 H, OH or OR 5 and R 5 is alkyl or aryl or R., form a cycloalkenyl or oxa-cycloalkenyl radical with R 3 .
- the a-unsaturated etones contained as stabilizers in the preparation according to the invention surprisingly make it possible to raise the peroxydicarbonate preparations with SADT temperatures (soap accelerating decomposition temperature) to temperatures above 0 ° C. and even increase the SADT temperatures for the composition reach that can be at + 10 ° C or higher.
- SADT temperatures sin accelerating decomposition temperature
- the alkyl or / and alkenyl groups preferably have 1 to 6 or 2 to 6 C atoms.
- a particularly preferred compound of the general formula I contains, as R., a propenyl radical, as R 2 and R 3 each a hydrogen atom and as R 4 an OH group or an O-alkyl radical. Sorbic acid and its methyl and ethyl esters are even more preferred.
- the compound of the general formula I contains a phenyl radical as R and a hydrogen atom as R 2 and R 3 .
- a phenyl radical as R
- a hydrogen atom as R 2 and R 3 .
- cinnamic acid and its ethyl and methyl esters are particularly preferred.
- the compound of the general formula I contains an oxa-cycloalkenyl-5 ring which is formed by R T and R 3 together with the double bond.
- furan-2-carboxylic acid and its methyl and ethyl esters are particularly preferred.
- the peroxydicarbonates used in the composition according to the invention are the compounds in which R is in each case an aliphatic, cycloaliphatic or aromatic group with up to 18
- the aliphatic Groups can consist of straight-chain or branched alkyl or alkenyl radicals from cycloalkyl radicals or aromatic groups.
- suitable groups for R are methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, t-butyl, isobutyl, hexyl, octyl, neopentyl, 2-ethylhexyl, capryl, lauryl, myristyl, cetyl, stearyl , Allyl, methallyl, crotyl, cyclohexyl, t-butylcyclohexyl, t-amylcyclohexylbenzyl, phenylethyl, phenylbutyl and the corresponding known radicals substituted with halogen atoms and / or nitro groups.
- Preferred peroxydicarbonates are selected from the group consisting of diethyl peroxydicarbonate, di-n-butyl peroxydicarbonate, diisobutyl peroxydicarbonate, di-sec-butyl peroxydicarbonate, di-2-ethylhexyl peroxydicarbonate, di-n-propyl peroxydicarbonate and diisopro nyl peroxydate carbonate.
- Ethylhexyl peroxydicarbonate in the composition according to the invention is particularly preferred.
- composition according to the invention are known and can be obtained by the methods described.
- the preparations according to the invention are preferably free from substantial amounts of solvent and can be prepared by simply mixing the constituents. Therefore, liquid peroxydicarbonates are preferred in which the compound of general formula I can be dissolved directly. However, it is also possible to use dilute peroxydicarbonates, which are then mixed with solutions of the compound of the general formula I to prepare the stabilized composition.
- Suitable solvents are the solvents commonly used for peroxydicarbonates, such as phthalic acid esters and hydrocarbons. However, solvents are generally less desirable for use as polymerization initiators and are therefore not preferred.
- the preparations according to the invention have, in particular, significantly increased SADT values and therefore significantly reduce the problems associated with the storage and transport of these peroxides. The following examples illustrate this. The SADT values were determined in accordance with the Recommendations on the Transport of Dangerous Goods, United National Nationales, 2nd Edition 1995, Part II, pp. 286-287.
- Examples 1 to 6 1) 1% by weight of ethyl sorbic acid is dissolved in technically pure ethylhexyl peroxydicarbonate (content, 99.2%) and this solution is subjected to the SADT test at + 5 ° C. The solution remains stable for 1 5 days, i.e. the SADT is> 5 ° C.
