Patent ID: 6964937

Claim:
A process for making a supported bimetallic catalyst suitable for use in the production of homopolymers and copolymers of ethylene with a bimodal molecular weight distribution in a single reactor, the process comprising: (A) contacting a support material with an organomagnesium component; (B) contacting the contact product of (A) with an aldehyde having the general formula (II): R 3 —CO—R 4 (II) wherein R 4 is a hydrogen, and R 3 is selected from the group consisting of aliphatic groups containing 1 to 10 carbon atoms, and aromatic groups containing 6 to 12 carbon atoms; (C) contacting the contact product of (B) with a non-metallocene transition metal component to obtain a catalyst intermediate; and (D) contacting the catalyst intermediate with at least one aluminoxane component and a metallocene component.
