Abstract

Abstract The polypropylene‐based compatibilizers, polypropylene‐g‐maleic anhydride (PP‐MAH), polypropylene‐g‐maleic anhydride/styrene (PP‐St/MAH), and polypropylene‐g‐acrylic acid (PP‐AA), were prepared by a high energy irradiation method. The compatibilizing effect of newly prepared graft copolymers on immiscible PP/Nylon6 blends has been studied by means of UTM, SEM and DSC techniques. The results indicate that PP‐MAH and PP‐ St/MAH are more effective compatibilizers for PP/Nylon6 blends than PP‐AA, and the compatibilizing effect on PP/Nylon6 blends depends on molecular structure of the compatibilizers and the composition of the blends.
