Vinyl monomers are effectively polymerized in the presence of bis(Et acetoacetato)copper (II) [14284-06-1]–Na tetraphenylborate [143-66-8] system, although neither component used alone showed any catalytic activity. The initiator system shows high activity in CHCl3 or MeCN, but more polar solvents, e.g., DMF and DMSO, caused a very slow polymerization rate. Halogen compound additives markedly accelerated the polymerization in the presence of the binary systems, but phenylacetylene [536-74-3] and 18-crown-6 [17455-13-9] retarded the polymerization Polymerization with the binary systems was propagated by a radical mechanism. Kinetics of polymerization of Me methacrylate [80-62-6] show that chain transfer reaction of the polymer radical to the catalyst components is negligible.
