Dinuclear metallocene complexes as catalyst precursors for homogeneous ethylene polymerization
Four dinuclear alkylidene-bridged zirconocene complexes were synthesized applying hydrozirconation reaction of alpha,omega-dienes with the "Schwartz' reagent" and tested for the polymerization of ethylene. The polyethylenes obtained with alkylidene-bridged dinuclear complexes showed higher molecular weights M-w and polydispersities revealing that more catalytically active species exist in the polymerization system.
