Catalysts of chain transfer to monomer in radical polymerization: Catalyst structure and donor-acceptor and redox properties

Information is presented on the catalytic properties of macrocyclic and polychelate complexes of cobalt in the reaction of methyl methacrylate polymerization. The catalytic activities of these compounds are compared with their donor-acceptor and redox properties.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 25, No. 6, pp. 698–704, November–December, 1989.The authors wish to express their appreciation to E.-G. Eger for kindly furnishing samples of the cobalt-alkyl and nickel compounds.
