Abstract
PURPOSE: A highly active catalyst for the stereoregular polymerization of olefins, composed of a specified solid catalyst component, an arganometallic compound and a heterocyclic carboxylate containing N, S or O.
CONSTITUTION: Title catalyst is composed of (A) a solid catalyst composition, prepared by treating a solid component with a L-Cl (wherein L is B, Si, etc.) bond-containing compound, an organometallic compound and (B) a heterocyclic carboxylate containing N, S or O; said solid component resulting from the reaction of a solid, a Ti compound of formula III (wherein R4 is R1) and a heterocyclic or hydrocarbon carboxylate, containing N, S or O; said solid being the product from the reaction between 1mol, based on Mg described hereafter, of the product from the reaction of an organic Mg compound of formula I (wherein M is Al, Zn, B or Be; R1, R2 each is 1W20C hydrocarbon group; X is halogen; α, p, q, r ≥0; β>0; p+q+r=mα+2β, wherein m is a valency of M) with an electron-donor such as an ether or a ketone, and 0.01W100mols of a Si-H bond-containing Chlorosilane compound of formula II (wherein R3 is R1; 0<1≤2; b>0; a+b≤4).
