Gama radiation-induced graft copolymerization of N-p-hydroxyphenylmaleimide onto polypropylene films

Polypropylene (PP) films were grafted with N-p-hydroxyphenylmaleinide using γ-radiation. The effect of both monomer concentration and dose rate on the degree of grafting was measured. Characterization of the grafted PP films included IR spectroscopy, X-ray diffraction, mechanical properties, thermal stability and surface topology and the dyeing characteristics of the grafted films with different dyes were also investigated.
