Over the past two decades there has been intense interest in late metal-catalyzed polymerizations of ethylene and polar vinyl monomers. We report in this contribution a detailed mechanistic study of the copolymerization of ethylene with vinyl trialkoxysilanes catalyzed by Pd(II) diimine complexes. These studies elucidate fully the details of chain propagation and a unique chain transfer process occurring through beta-silyl elimination. Kinetic studies establish negligible rate retardation relative to ethylene homopolymerization despite the occurrence of chelate intermediates.
