Abstract

PURPOSE: To prepare a highly stereo-regular α-olefin polymer by using a highly active polymerization catalyst comprising a specific activated titanium component and an organo-aluminum compound.
CONSTITUTION: α-Olefin is polymeized in the presence of a catalyst comprising (A) an activated titanium component obtained by (1) co-crushing (a) magnesium halide (pref. anhydrous magnesium chloride), (b) a complex of aluminum halide and an organic acid ester (e.g. prepared by mixing aluminum trichloride with methyl benzoate at room temperature) at 0-90°C for 2-100 hours (the co-crushing may be conducted by adding the component (a) to the homogeneous mixture of (b) and (c)), (2) dispersing the product in titanium tetrachloride at room temperature to 150°C, (3) separating the solid component from the dispersion, and (4) washing the solid component with inert solvent, and (B) an organo-aluminum compound.
