Catalyst component for polymerization of olefins, polymerization catalyst and process of polymerization of olefins by using the same

摘要

A metallocene compound may be used as a catalyst component for the polymerization of olefins. The compound is stable to air and moisture so that it generates no hydrogen halide by hydrolysis and is easily handled, and it has high storage stability and high catalyst activity. Specifically, the catalyst component for the polymerization of olefins comprises a transition metal composition represented by the general formula [1] and [2]:(Ra Cp)m (R'b Cp)M(-X-Ar-Yc)4-(m+n) [1]R''(Rd Cp)(R'e Cp)M(-X-Ar-Yc)2 [2]wherein M is Ti, Zr or Hf; each of (RaCp), (R'b Cp), (Rd Cp) and (R''e Cp) is a radical having the cyclopentadienyl skeleton; R'' is a radical that links (Rd Cp) and (R'e Cp); (-X-Ar-Yc) is a grouping in which the aromatic ring Ar substituted by a specified radical Y bonds to M through an oxygen or sulphur atom X.
