CATALYST FOR STEREOREGULAR POLYMERIZATION OF ALPHA-OLEFIN AND PROCESS FOR PRODUCING STEREOREGULAR ALPHA-OLEFIN POLYMER |
摘要 |
<p>A catalyst for stereoregular polymerization of alpha -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 alpha -olefin stereoregular polymerization ability and an organometallic compound (C), and a process for producing a stereoregular alpha -olefin polymer which comprises polymerizing alpha -olefin with said catalyst. <IMAGE></p> |
