Abstract

In the field of olefin coordination polymerization there is a demand to design new catalysts with high activity, high stability, controlled polymer structure and properties. Late transition metal catalysts have attracted much attention due to their ease of modification, the capability of controlling branching-structure of olefin polymer and tolerance towards polar monomers. In this paper, we summarized the recent work of our group on designing nickel catalysts with [ N,N ]-bidentate ligands for olefin polymerization, including monoamidinate, α-diimine, 2-amine pyridine, amine-imine, β-diimine and anilido-imine nickel catalysts. Living polymerization of olefins could be successfully realized via subtle modification of catalyst structure.
