The radiation-induced graft copolymerization of N-vinyl-2-pyrrolidone (NVP) onto polypropylene films was investigated using the mutual method. The grafted polymer was modified with prepared โฃ,โค-unsaturated nitrile (Scheme 1). The water uptake of the grafted and modified grafted films was found to in

Liquid phase ultraviolet irradiation in the presence of benzophenone as a photosensitizer and barium hydroxide as a pH controller were used to graft the mixtures of acrylic acid and acrylamide to a polypropylene surface. The surface of the grafted polypropylene samples were characterized by Fourier
Polypropylene (PP) รlms were grafted with N-phenylmaleimide using c-radiation. The e โ ect of both monomer concentration and dose rate on the degree of grafting was measured. Characterization of the grafted PP รlms included IR spectroscopy, X-ray spectroscopy, electrical conductivity, mechanical prop
