摘要：

A number of bulky, nonenolizable Pd(II) and Ni(II) imine-phosphine complexes have been synthesized and tested in the ethylene polymerization. These catalysts show improved temperature stability with respect to the corresponding diimine complexes. Nickel imine-phosphine precatalysts containing gem-dimethyl substituent a to phosphorus display moderate activity and produce substantially higher molecular weight polyethylene compared to the corresponding enolizable complexes.
