Abstract

PURPOSE: To obtain a polymer having high stereoregularity, without requiring the removal of catalyst residues or amorphous polymers, by polymerizing an olefin in the presence of a catalyst consisting of (A) a titanium-containing solid component and (B) an organometallic compound.
CONSTITUTION: An olefin or its mixture is (co)polymerized in the presence of a catalyst consisting of (A) a titanium-containing solid component obtained by pulverizing an electron donor adduct of a magnesium halide with a tetravalent titanium compound and (B) an organometallic compound of the formula M1 Al R1 R2 R3 R4 or M2(Al R1 R2 R3R4)2 (M is alkali metal; Al is aluminum; M2 is alkaline earth metal; R1, R2, and R3 are H, 1W20C hydrocarbon groups; R4 is 1W20C hydrocarbon group). The electron donor adduct is obtained by reacting a magnesium halide with an electron donor compound in an inert hydrocarbon solvent.
