A method for producing novel triarylphosphine or triarylarsine compounds and their use ?- olefin polymerization catalysts and ?- olefin copolymer . .

摘要

PROBLEM TO BE SOLVED: To raise the activity of polymerization catalyst in the copolymerization of α-olefin with a polar group-containing monomer, especially the copolymerization with a (meth)acrylic acid-based monomer.;SOLUTION: New triarylphosphine and triarylarsine compounds, each having a specific structure, are made to be a catalyst of the copolymerization of α-olefin with a polar group-containing monomer, by using a metal complex as a ligand in a catalyst composition. By the copolymerization catalyst with high catalytic activity, the industrialization of the copolymerization of α-olefin with a (meth)acrylic acid-based olefin is attained, the olefin copolymer thus obtained excels in mechanical and thermal physical properties, and is applicable as various kinds of useful molded products.;COPYRIGHT: (C)2010,JPO&INPIT
