ABSTRACT:
A method for making novel catalysts for the polymerization of olefins, said catalysts being prepared by reacting a metal dihalide with certain transition metal compounds and reacting that product with certain organoaluminum compounds wherein in one embodiment that product is contacted with a halide exchanging source selected from halides of Groups IVA and VA of the Periodic Table and wherein in another embodiment a third component, such as an electron donor, is included in the reaction between the metal dihalide and the transition metal compound.
