摘要

Abstract

The

-imino-ketone nickel catalyst is an emerging versatile platform that is easy to prepare and allows for the production of branched high molecular weight functionalized polyethylenes. However

study on this catalyst system is rare thus far. In this contribution

by introducing different backbones

flexible and rigid axial substituents into the

-imino-ketone framework

a family of cationic nickel catalysts were synthesized and fully characterized. Without the addition of any activator

systematic studies on ethylene polymerization and copolymerization with polar monomers were performed to explore the influence of both backbone and axial substituent on catalytic activity

polymer molecular weight

branching density and incorporation. In particular

owing to the unique semi-opening feature of the

-imino-ketone framework

the preferred nickel catalyst exhibited high activity of 175 kg·mol

−1

·h

−1

to produce functionalized polyethylene with molecular weight of 13.4 kg·mol

−1

and co-monomer incorporation of 2.9 mol%.
