Abstract
The synthesis and characterization of 15 new, unbridged metallocene dichlor ide complexes of the type (L)(Ind)ZrCl2, (L = omega-phenylalkyl substituted cyclopentadienyl or 1-phenylsilyl substituted indenyl; Ind = indenyl) and (L')(Flu)ZrCl2(L' = 1-benzyl substituted indenyl or 2-benzyl substituted in denyl; Flu = fluorenyl) are reported. After activation with methyl aluminox ane (MAO), these complexes are highly active catalysts for homogeneous ethy lene polymerization. The influence of various substituents on the catalyst activities and the polymer properties are discussed. (C) 2000 Elsevier Scie nce B.V. All rights reserved.
