Cyano-functionalized polyethylenes from ethylene/acrylamide copolymerization.

ABSTRACT: Synthesizing functionalized polyethylenes via ethylene coordination copolymerization with fundamental low-cost vinyl polar monomers provides a very attractive approach. However, it is also very challenging as the functional group (FG) to be introduced onto the polyolefin chain is directly derived from the corresponding vinyl polar monomers (CH₂ = CH-FG), which often cause catalyst poisoning due to the FG coordination to active metal center and β-X elimination during catalysis, etc. It is especially true for the synthesis of cyano-functionalized polyethylenes (PEs) via ethylene/acrylonitrile copolymerization, which can only rely on Pd catalysis with low activity. Here we present an approach utilizing binuclear Ni catalysis for ethylene/acrylamide copolymerization and the synthesi
