ABSTRACT:
A process for polymerizing or copolymerizing .alpha.-olefins having at least 3 carbon atoms or copolymerizing .alpha.-olefins having at least 3 carbon atoms with not more than 50 mole % of ethylene in the presence of a catalyst composed of an organometallic compound of a metal of Groups I to III of the periodic table and a titanium catalyst component supported on a halogen-containing magnesium compound, said titanium catalyst component being a solid reaction product obtained by treating (i) a mechanically copulverized product of a halogen-containing compound and an organic acid ester with (ii) an organo-metallic compound of a metal of Groups I to III of the periodic table, and then reacting the resulting solid product with (iii) a titanium compound in the absence of mechanical pulverization.
