SLURRY POLYMERIZATION WITH UNSUPPORTED LATE TRANSITION METAL CATALYST

摘要

A slurry ethylene polymerization process is disclosed. The process uses an unsupported late transition metal catalyst that comprises an acenaphthene N,N'-bis(arylimine) ligand. The process is conducted in the presence of a non-aromatic hydrocarbon diluent. The process produces polyethylene having high molecular weight in powder form and it gives high catalyst activity at relatively high temperatures.
