ABSTRACT:
A catalyst composition for polymerizing alpha-olefins is prepared by treating a carrier containing OH groups with an organomagnesium composition and contacting the thus-formed magnesium-containing carrier with a solution of at least one tetravalent vanadium compound. Alternatively, the solution may also contain at least one tetravalent titanium compound in addition to the vanadium compound, thereby producing catalysts containing both, vanadium and titanium. Also disclosed is a process for polymerizing alpha-olefins in the presence of the catalysts of the invention.
