Abstract
Procedeul de polimerizare a alfa-olefinelor consta în faptul ca, se supune reactiei de polimerizare cel putin o alfa-olefina la temperatura de 0,,,,120 degree C si o presiune de 1,4.....12,2 kgf/cm la puterea 2 în absenta apei sau a altor otravuri absenta apei sau a altor otravuri catalitice, în prezenta unui sistem catalitic constituit din (A) un compus organic de aluminiu si (B) un component solid care este produsul de reactie al compusilor (1) cel putin o halogenura sau un halogen alcoolat de titan (IV) continînd 1....20 atomi de carbon în grupa alcolat; (2)cel putin un donor de electroni , ales dintr-o grupa formata dintr-un alchil ester cu 1....5 atomi de carbon, al unui acid monocarboxilic aromatic, eventual substituit cu cel putin un halogen, hidroxil, oxo, alchil, alcoxi: (3), cel putin un produs pretratat insolubil în hidrocarbura continînd magneziu ales dintre (a) cel putin un compus cu formula Mg(OR1)n (ORla puterea 2)2-n în care R1 si R2 sunt radicali de hidrocarbura identici sau diferiti cu 1....20 atomi de carbon si n este cuprins.......The process for the polymerization of alpha-olefins consists in subjecting at least one alpha-olefin to a polymerization reaction at a temperature of 120 DEG C. and a pressure of 1.4 ..... 12.2 kgf / cm at power 2 in the absence of water or other poisons lacking water or other catalysis poisons in the presence of a catalytic system consisting of (A) an organic aluminum compound and (B) a solid component which is the reaction product of the compounds 1) at least one halide or a titanium alcoholate (IV) containing 1 to 20 carbon atoms in the alcoholate group; (2) at least one electron donor selected from the group consisting of an alkyl ester of 1-5 carbon atoms, an aromatic monocarboxylic acid optionally substituted by at least one halogen, hydroxyl, oxo, alkyl, alkoxy: (3) at least one hydrocarbon insoluble pretreated product containing magnesium selected from (a) at least one compound of the formula Mg (OR 1) n (OR a 2) 2 n wherein R 1 and R 2 are hydrocarbyl identical or different with 1 to 20 carbon atoms and n is comprised ...
