Bimetallic metallocene alumoxane catalyst system and its use in the preparation of ethylene copolymers
A catalyst system comprising certain bimetallic metallocenes and an alumoxane is provided together with a process for the preparation of high molecular weight ethylene-alpha olefin elastomers and ethylene-alpha-olefin nonconjugated diolefin elastomers wherein the requisite monomers are polymerized in the presence of the bimetallic metallocene/alumoxane catalyst system.
