Polypropylene (PP) was grafted with acrylamide using benzoyl peroxide (BP) as an initiator by melt mixture. Effects of various parameters such as monomer and initiator concentration, reaction time, and reaction temperature on degree of grafting were studied. The graft copolymers were characterized by irradiation (IR), electron spectroscopy for chemical analysis (ESCA), wide-angle x- ray diffraction (WAXD), DSC, and contact angle studies.
