Patent ID: 6855654

Claim:
A process for preparing a bimetallic catalyst, the process comprising: (a) providing a supported non-metallocene catalyst by: (i) preparing a slurry of a dehydrated support in a non-polar hydrocarbon; (ii) contacting the slurry of (i) with an organomagnesium compound RMgR′, where R and R′ are the same or different C 2 -C 12 alkyl groups; (iii) contacting the slurry of (ii) with a non-metallocene compound of a Group 4 or Group 5 transition metal; and (iv) drying the product of (iii) to obtain a supported non-metallocene catalyst; (b) contacting a slurry of the supported non-metallocene catalyst in a non-polar hydrocarbon with a solution of a metallocene compound and a C 1 -C 8 alkyl alumoxane in an aromatic solvent; and (c) drying the product of (b) to obtain a supported bimetallic catalyst.
