Abstract

The substituted indenyl metallocene complexes (1-C_6H_5CH_2Ind)_2MCl_2(M=Ti(1),Zr(2)) and (1-C_6H_5CH_2Ind)CpMCl_2(M=Ti(3),Zr(4)) were synthesized and characterizd by IR、~1H NMR, EI-MS and elemental analysis. It is found that the compounds(2) and (4) could be used for catalytic polymerization of ethylene in the presence of MAO with products of [M]_η=(31.4~39.5)×10~4.
