Abstract

PURPOSE: To obtain an olefin polymerization catalyst capable of producing a highly stereoregular polymer, by combining an organic Al compound with a solid catalyst component obtained by contacting a solid component composed essentially of Ti, Mg and a halogen with an Si compound and an organic Zn compound.
CONSTITUTION: The objective catalyst is composed of (A) a solid catalyst component produced by contacting (i) a solid component containing Ti, Mg and a halogen as essential components [e.g. a composition containing Ti(OC2H5)Cl3, dialkoxymagnesium and an Al halide as essential components], (ii) an Si compound of formula (R1 and R2 are hydrocarbon residue; X is halogen; 0≤m≤3; 0≤n≤3; 0≤m+n≤3) [e.g. (CH3)Si(OCH3)3] and (iii) an organic Zn compound [e.g. (CH3)2Zn or (C2H5)Zn(OCH3)] and (B) an organic Al compound (e.g. trimethylaluminum).
