Homo- and Copolymerization of Ethylene and Norbornene with Anilido–Imine Chromium Catalysts

A series of anilido–imine chromium complexes have been used as precursors to catalyze homo- and copolymerization of ethylene and norbornene. The chromium complexes activated with methylalumoxane (MAO) exhibit good activities for homopolymerization of ethylene (E) to produce linear polyethylene and m...
