✦ Synopsis

Graft copolymerization of acrylonitrile (AN) and 4-chlorostyrene (4-Clst) onto ethylenepropylene-diene terpolymer ( EPDM ) was carried out using benzoyl peroxide as initiator.

The effects of EPDM content, initiator concentration, solvent, mole ratio of 4-Clst to AN, reaction time, and reaction temperature on the graft copolymerization were examined. It was found that the light resistance, weatherability, and thermal stability of the acrylonitrile-EPDM-4-chlorostyrene graft copolymer were considerably better than those of acrylonitrilebutadiene-styrene copolymer.
