摘要

PROBLEM TO BE SOLVED: To provide a compound which is other than a compound of the group 13 and, when used as a cocatalyst component for activation, can form an addition polymerization catalyst exhibiting high polymerization activity; an addition polymerization catalyst component comprising the compound; an addition polymerization catalyst exhibiting a high polymerization activity and prepared by using the compound; and a method for efficiently producing an addition polymer by using the catalyst. ;SOLUTION: The compound is represented by formula [1] (wherein M is an atom of the group 3-12 or of the lanthanoid series; T is an atom of the group 14, 15, or 16; R1 is an electron-attracting group or a group having an electron-attracting group; R2 is a hydrocarbon group; m is the atomic valence of M; t is the atomic valence of T; and n is 1 or higher). The addition polymerization catalyst component comprises the compound. The addition polymerization catalyst is prepared by using the compound. The method for producing an addition polymer uses the catalyst.;COPYRIGHT: (C)2001,JPO
