CATALYTIC COMPONENTS FOR THE POLYMERIZATION OF OLEFINS, POLYMERIZATION CATALYSTS, AND PROCESS FOR POLYMERIZING OLEFINS BY USING THE SAME

摘要

Metallocene compounds which are used as catalytic components for the polymerization of olefins, do not generate hydrogen halide, are stable in air and water, easy of handling and excellent in storage stability, and exhibit a high catalytic activity. Specifically, transition metal compounds represented by the general formulas (1): (RaCp)m(R'bCp)nM(-X-Ph-Yc)4-(m+n) and (2): R''(RdCp)(R'eCp)M(-X-Ph-Yc)2 wherein M is Ti, Zr or Hf; (RaCp), (R'bCp), (RdCp) and (R'eCp) are each a group having a cyclopentadienyl skeleton; R'' is a group forming a bridge between (RdCp) and (R'eCp); and (-X-Ph-Yc) is an aromatic group Ph substituted by specific groups Y and bonded to M through an oxygen or sulfur atom X.
