Zusammenfassung:	Catalyst compositions are disclosed which are a combination of a supported titanium compound such as titanium tetraisopropoxide supported on magnesium dichloride and at least one other supported metallic catalyst such as dicyclopentadienyl zirconium dichloride supported on alumina and a cocatalyst such as aluminoxane. These catalysts are useful in the polymerization of alpha -olefins.
