METALLOCENE COMPLEX AND POLYMERIZATION CATALYST COMPOSITION CONTAINING THE SAME

摘要

Disclosed are a metallocene complex represented by the general formula (I), (II) or (III), and a polymerization catalyst composition containing such a metallocene complex. In the formulae (I), (II) and (III), M represents a lanthanoid element, scandium or yttrium; CpR's independently represent an unsubstituted or substituted indenyl; CpR' represents an unsubstituted or substituted cyclopentadienyl, indenyl or fluorenyl; Ra-Rf independently represent a hydrogen or an alkyl group having 1-3 carbon atoms; X and X' respectively represent a hydrogen atom, a halogen atom, an alkoxide group, a thiolate group, an amide group, a silyl group or a hydrocarbon group having 1-20 carbon atoms; L represents a neutral Lewis base; w represents an integer of 0-3; and [B]- represents a non-coordinating anion.
