摘要
A process for preparing an olefin polymer or copolymer by polymerizing or copolymerizing an olefin containing at least 3 carbon atoms which may contain at most 10 mole % of ethylene and/or a diene, in the presence of a catalyst composed of (A) a solid titanium catalyst component prepared by (1) reacting a mechanically pulverized product of an organic acid ester and a halogen-containing magnesium compound, with an active hydrogen-containing organic compound in the absence of mechanical pulverization, (2) reacting the resulting reaction product with an organometallic compound of a metal of Groups I to III of the periodic table in the absence of mechanical pulverization, and (3) washing the resulting solid reaction product with an inert organic solvent, reacting the washed solid reaction product with a titanium compound in the absence of mechanical pulverization, and separating the solid from the reaction system, and (B) an organometallic compound of a metal of Groups I to III of the periodic table; and a catalyst used therefor.
