Abstract

PURPOSE: To obtain a highly stereoregular olefin polymer by keeping polymer yields per Ti atom on a high level without the necessity for using an electron donor such as an aromatic carboxylic ester in the polymerization system by using a catalyst system containing a specified transition metal compound.
CONSTITUTION: An olefin is polymerized by using a catalyst system containing a complex obtained by bringing a product of contact between an Mg compound of formula I (wherein R' is a 1-10C alkyl, a 4-10C cycloalkyl or an aryl; X is a halogen atom; and m is 0-2) and a Ti compound of formula II (wherein R2, R3 and R4 are each a 1-10C alkyl, a 4-10C cycloalkyl or an aryl) into contact with an organoaluminum compound of formula III or IV (wherein R5 and R6 are each a hydrocarbon group, X and X' and each a halogen atom and r is 0-2) and a metallocene of formula V or VI (wherein C5R7 q is a cyclopentadienyl group, and M is a transition metal element of Group IVA, VA or VIA).
