The synthesis is described of dissymtric alkylidene bridged dinuclear metallocene complexes of titanium, zirconium and hafnium and some of the corresponding mononuclear reference complexes. The influence of structural parameters on the polymerization behavior of the MAO activated complexes is systematically investigated for homonegeous ethylene polymerization. The dinuclear catalysts show higher polymerization activities than a mixture consisting of analogous mononuclear reference catalysts. The polethylenes obtained from dinuclear complexes have higher polydispersities than those that were produced with mononuclear complexes.
