Abstract
Cationic zirconium complexes of formula [Cp(2)ZrBz](+), [Cp'ZrBz(2)](), or [ZrBz(3)](+) (Cp = eta(5)-C5H5, Cp' = Cp or eta(5)-C(5)Me(5), Bz = CH(2)C(6)H5) have been tested as catalysts for the polymerization o f ethylene and a-olefins. The catalyst performances have been compared with regard to polymer productivities, molecular weights and stereore gularities, and tentatively correlated to the structure of the ionic a ctive species.
