Abstract
PURPOSE: To prepare a highly stereoregular polyolefin having a high powder bulk specific gravity in a high yield, by polymerizing an olefin in the presence of a catalyst system conisting of a specific solid component and an organoaluminum compound.
CONSTITUTION: An olefin is polymerized in the presence of a catalyst system consisting of (A) a solid component, obtained by reacting (a) a reaction product with (b) one or two or more types of titanium halides in the presence of an organic ester at 20W120°C for 5 min W20hr, and (B) an organoaluminum compound in the presence or absence of an inert solvent at 30W200°C and a pressure ranging from normal one to 100kg/cm2. The reaction product (a) is obtained by reacting a chain or cylic hydropolysiloxane having structural units of formula (R' is alkyl, aryl, aralkyl, alkoxy, or alloxy group; a is an integer 0, 1, or 2; b is 1, 2, or 3; a+b≤) with (ii) a Grignard reagent at 50W100°C for 1W5 hr
