Abstract:	Benz[f]indenyl zirconium complexes have been successfully synthesized and characterized. Their catalytic activities were evaluated for the polymerization of ethylene. The complexes combined with MAO can be highly active single site catalysts, which display activities comparable with that of the Cp₂ZrCl₂/MAO system and provide very high molecular weight polyethylenes. The melting point of the polymers indicates the formation of linear polyethylene.

Keywords:	Benz[f]indenyl Zirconium Cyclopentadienyl Ethene Polymerization
