Abstract

See full text

The copolymerization of ethylene with a cyclic mono olefin (such as norbornene) is conducted in the presence of a catalyst system comprising a bridged hafnocene catalyst and a three part activator. The catalyst system provides excellent activity at high polymerization temperatures. Copolymers produced according to this invention have unique microstructure (with methyl branching being observed) and unique rheology.
