ABSTRACT:
Olefin polymerization catalyst useful in preparation of polyolefins of broad molecular weight distribution comprising (a) a component prepared by reacting an organoaluminum compound with a mixture comprising a titanium compound, a zirconium compound, and a vanadium compound; and (b) an organoaluminum promoter. The (a) component can be further treated with a deactivating agent. The olefin polymerization performance of the (a) component can be varied depending on the choice of promoter and deactivating agent.
