On the peroxide cure of EPDM and EPM, the effects of various vinyl compounds having different functionalities, chain length between vinyl groups, and electron density of c=c double bond were studied.It was found that polyfunctional vinyl compounds (ethylene-dimethacrylate, trimethylolpropantrim-ethacrylate, N, N′-m-phenylenebismaleimide, N, N′-methylenebisacrylamide were more effective than monofunctional vinyl compounds (laurylmethacryrate, maleimide, phenylmaleimide, acrylamide).The dimethacrylates having the shorter chain length between the end vinyl groups and the vinyl compounds having the larger value of +e behaved the more effectiveness as the crosslinking additive on the peroxide cure of EPDM and EPM.
