Synthesis and characterization of unbridged metallocene dichloride complexes with two differently mono-substituted indenyl ligands and their application as catalysts for the polymerization of ethene and propene
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 complexes are characterized by H-1 and C-13 NMR spectroscopy and mass spectrometry and tested for the catalytic polymerization of ethene and propene. The polymerization results and the polymer properties indicate a considerable influence of the catalyst structure on the polymerization behavior.
