Abstract

PURPOSE: To prepare a highly stereoregular polyolefin without the ash-removing process, by using a catalyst system comprising an organoaluminum compound and a component provided by contacting a magnesium compound with the adduct of a tetravalent titanium compound with a specific ether compound.
CONSTITUTION: A desired polymer is prepared by polymerizing an olefin (e.g. ethylene) in the presence of a polymerization catalyst comprising (A) an organoaluminum compound (e.g. trialkylaluminum compound) and (B) a particulate solid provided by mechanically contacting the addition reaction product of (a) a tetravalent titanium compound (e.g. titanium tetrahalide) with (b) a compound expressed by the formula (RI is alkyl; RII is H or alkyl), with (c) a magnesium dihalide (e.g. magnesium chloride).
