Branched Polyethylene Synthesized by Salicylaldiminato Nickel Complexes with an Ethereal Donor Group

Many late-transition-metal catalysts have been developed
for the
synthesis of branched polyethylene. However, the methods for the synthesis
of low molecular weight and highly branched polyethylene are limited.
Here we report the facile synthesis of a series of salicylaldiminato
nickel complexes with an ethereal donor hemilabile group and their
application in ethylene polymerization to produce low molecular weight
highly branched polyethylene effectively.
