CATALYST FOR STEREOREGULAR POLYMERIZATION OF ALPHA-OLEFIN AND PROCESS FOR PRODUCING STEREOREGULAR ALPHA-OLEFIN POLYMER

摘要

A catalyst for stereoregular polymerization of α -olefins obtained by a process comprising contacting modified particles (A) obtained by contacting dried particles (a) with an organometallic compound (b), then with a compound (c) having a functional group containing an active hydrogen or non-proton donative Lewis basic functional group, and an electron withdrawing group, with a transition metal compound (B) having an α-olefin stereoregular polymerization ability and an organometallic compound (C), and a process for producing a stereoregular α-olefin polymer which comprises polymerizing α-olefin with said catalyst.
