A graft terpolymer of maleic anhydride (MAH) and styrene (St) on ethylene-propylene-diene terpolymer (EPDM) was obtained using azobisisobutyronitrile (AIBN) as an initiator in toluene. The effects of EPDM concentration, mole ratio of St to MAH, reaction time, reaction temperature, initiator concentration, and solvent on the graft copolymerizations were examined. The synthesized maleic anhydride-EPDM-styrene graft terpolymers (MAES) were identified by IR spectra. It was found that the thermal stability of the MAES was not good when compared to that of acrylonitrile-butadiene-styrene copolymer (ABS), but the light resistance and weatherability of MAES were superior to those of ABS.
