The radical copolymerizations of chloroprene (CP) and α-cyanoethyl acrylate (CEA) were carried out in toluene at 45°C in moisture free atmosphere by use of dry nitrogen. Microstructures in the copolymers have been examined by 1H and 13C nuclear magnetic resonance and Fourier transform infra-red spectroscopy. They showed that the copolymer, whose composition ratio was nearly CP/CEA = 1/1 (mol), possessed predominantly-(CP-CEA)-repeating unit in which CP had the 1,4 unit. A reaction mechanism by way of Diels-Alder intermediate was discussed for this regular copolymerization. © 1997 Elsevier Science Ltd.
