GROUP IVB, VB AND VIB METAL HYDROCARBYLOXIDES, WITH ALUMOXANE FOR OLEFIN POLYMERIZATION

摘要

The invention is a catalyst system including a Group IVB, VB or VIB transition metal hydrocarbyloxide component and an alumoxane component which may be employed in liquid, slurry or bulk phase reactors to polymerize ethylene and alpha -olefins to produce a high molecular weight, narrow molecular weight distribution homo- and co-polymer.
