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

摘要

A catalyst for stereoregular polymerization of alpha -olefins which is obtained by a method comprising contacting dried particles (a) with an organometallic compound (b), subsequently contacting the resultant particles with a compound (c) which has a functional group having active hydrogen or serving as a non-proton-donating Lewis base and further has an electron-attracting group to obtain modified particles (A), and contacting the particles (A) with a transition metal compound (B) having the ability to stereoregularily polymerize an alpha -olefin and with an organometallic compound (C); and a process for producing a stereoregular alpha -olefin polymer which comprises using the catalyst to polymerize an alpha -olefin.
