We investigated the copolymerization of ethylene and alkyl acrylates and found that a Ni complex containing the ¡ - iminocarboxamide ligand can catalyze such copolymerization to form linear copolymers. Since this catalyst system needs low polymerization temperatures around 40 ° C because it lacks in high temperature tolerance, we further explored better Ni catalyst systems. We fi nally found that phosphinophenol - ligated neutral Ni complexes can catalyze copolymerization of ethylene and acrylates to produce highly linear copolymers at higher temperatures. By introducing methoxy groups into the ligand, we were able to improve the catalyst performance signi fi cantly in terms of catalyst activity, molecular weight of the copolymer, and acrylate content.
