Abstract

PURPOSE: To prepare a highly stereo-regular olefin polymer, by the use of a specific highly active catalyst comprising an active titanium component prepared from a compound having a carbon atom with two or more alkoxy groups, etc.
CONSTITUTION: A catalyst system for the polymerization of α-olefins, comprising (A) a solid component obtained by co-crushing (a) magnesium halide, (b) a complex of aluminum halide and an organic acid ester, and (c) a compound having a carbon atom bonded with two or more alkoxy groups (e.g. orthoacetic acid ethyl ester), and treating the product with titanium halide, (B) an organo-aluminum compound of formula (R is hydrocarbon, X is alkoxy, halogen, etc.; m is 1.5W3) and (C) an electron donor (e.g. organic acid ester, etc.).
