Abstract: Catalysts effective for the polymerization of olefins at high productivity formed upon mixing (1) a solution of a titanium tetrahydrocarbyloxide or a zirconium tetrahydrocarbyloxide and an organoaluminum halide with (2) a dihydrocarbylmagnesium compound alone or admixed with a minor amount of a trialhylaluminum and (3) combining the product obtained in (2) with a metal halide selected from a silicon tetrahalide and a titanium tetrahalide. The catalyst component thus produced can be combined with an organoaluminum compound as a cocatalyst component.
