The graft terpolymer of methacrylonitrile (MAN) and 2‐vinylnaphthalene (2‐VN) onto ethylene‐propylene‐diene terpolymer (EPDM) was synthesized in toluene using benzoyl peroxide (BPO) as an initiator. The effects of EPDM content, mole ratio of 2‐VN to MAN, reaction time, reaction temperature, and initiator concentration on the graft copolymerization were examined. The synthesized graft terpolymer was identified by IR and 1 H‐NMR spectroscopies. The light resistance, thermal stability, molecular weight, and tensile properties of the graft terpolymer were investigated by Fade‐o‐meter, thermogravimetric analysis, gel permeation chromatography (GPC), and a universal tensile machine (UTM). It was found that the light resistance and heat resistance as well as the tensile strength of the graft terpolymer are considerably better than those of the acrylonitrile‐butadiene‐styrene (ABS) terpolymer. © 1995 John Wiley & Sons, Inc.
