Patent

CA 2138572

A gas phase process for producing polyethylene containing long chain branches is disclosed and claimed. The polymerization process involves contacting ethylene under polymerization conditions in the gas phase and at a temperature above 65°C, with a catalyst composition which includes a) at least one bridged metallocene having at least two cyclic pi-bonded moieties in association with a metal atom, the cyclic pi-bonded moieties being joined together via a bridging linkage one or two atoms long, and b) an activating cocatalyst; the catalyst composition being effective to result in incorporation of an average of up to 3 long chain branches per 1000 carbon atoms in the main polyethylene chain.
