Abstract
The synthesis of unbridged metallocene dichloride complexes of the type Ind (#)Ind ' ZrCl2 (Ind(#) = 2-arylalkyl-substituted indenyl, Ind ' = 1-omega - alkenyl-substituted or 2-alkyl-substituted indenyl) is described. The compl exes are characterized by H-1 and C-13 NMR spectroscopy and mass spectromet ry and tested for the catalytic polymerization of ethene and propene. The p olymerization results and the polymer properties indicate a considerable in fluence of the catalyst structure on the polymerization behavior. (C) 2001 Elsevier Science B.V. All rights reserved.
