Abstract

PURPOSE: Using a catalyst consisting of a specific activated titanium solid catalyst, an organoaluminum compound and an electron donor, the polymerization of an α- olefin is conducted with high activity to produce a polymer with high stereoregularity.
CONSTITUTION: The catalyst used for polymerization is composed of (A) a solid catalyst component resulting from the reaction between (i) metallic magnesium, (ii) a tetraalkoxytitanium such as titanium tetramethoxide, (iii) an alcohol, preferably methanol, (iv) an electron donor such as an organic acid, e.g., benzoic acid, (v) titanium halide such as titanium tetrachloride, (B) an organoaluminum compound such as trimethylaluminum and (D) an electron donor wherein the amount of ii is 0.2W1mol per mole of component i, iii is 2W5mol, iv is 0.05W3mol and v is 1W 50mol.
