Abstract

A process for preparing highly stereoregular polyolefins in the presence of a catalyst which comprises (A) a titanium-containing solid catalyst component composed of an organic complex derived from (i) a magnesium halide (ii) an organo polysiloxane of the formula Q(Q2SiO)n SiQ3, (Q2SiO)n and/or x(Q2siO)nSiQ2X, (iii) an organic carboxylic acid ester, and (iv) a titanium compound of the formula Ti(OR)?x4-? and (B) an organoaluminum catalyst component of the formula R'mAl(OR')3-m .
