Bimetal catalysts with high activity

Methods of making mixed Ziegler-Natta/metallocene catalysts are disclosed. The methods include slurrying a dehydrated support in a hydrocarbon solvent, adding a dialkylmagnesium compound, then adding a non-metallocene group 4 or 5 metal compound, followed by adding a metallocene, an alumoxane, and o...
