Abstract

PURPOSE: To obtain the title highly stereoregular polymer without requiring removal of catalyst residues, by using a highly active catalyst comprising a component prepared through reaction of a titanium compound with a reaction product between a hydropolysiloxane and a Grignard reagent.
CONSTITUTION: An olefin is polymerized in the presence of a catalyst comprising (A) a solid component, obtained by reacting a reaction product between (a) a chain or cyclic hydropolysiloxane of the formula (R1 is hydrocarbon, etc.; a is 0, 1, or 2; b is 1, 2, or 3, a+b≤3) and (b) a Grignard reagent with (c) a titanium halide in the presence of 2W20l per gram of Mg in the product of an aromatic hydrocarbon solution and an organic acid ester, and (B) an organoaluminum compound.
