Abstract
The disiloxane-bridged zirconocene complexes, methyldisiloxanediylbis( cyclopentadienyl)zirconium dichloride and siloxanediylbis(cyclopentadi enyl)dimethylzirconium initiate the homopolymerization of ethene as we ll as the copolymerization of ethene and alpha-olefin with a modified methylaluminoxane as cocatalyst. The catalyst systems give reasonable activity but the molecular weight of polyethene decreases drastically with increasing polymerization temperature.
