Abstract

PURPOSE: To prepare a highly crystalline olefin polymer having high stereoregularity and a broad molecular weight distribution, and useful for extrusion molding, etc., by carrying out the polymerization of an olefin in the presence of a highly active catalyst comprising a titanium halide, a specific organoaluminum compound and an electron donative compound.
CONSTITUTION: Polyolefins having broad molecular weight distributions expressed by the curve (a) and (b) are prepared by polymerizing olefins (e.g. propylene) in the presence of a catalyst system comprising (A) a titanium halide (e.g. titanium tetrachloride), (B) an aluminum alkoxide compound expressed by the formula (R1 or H or 1W18C hydrocarbon; R2 is 1W18C hydrocarbon; X is halogen; 0<m<2, 0≤n<2 and 0<m+n≤2) and (C) an electron donative compound (e.g. ethyl benzoate). The curve (c) exhibits the molecular weight distribution of a polymer prepared by using diethylaluminum chloride in place of the component (B).
