Abstract

Radiation grafting of monomers onto suitable trunk polymers is a useful tool for tailoring new polymers for special purposes. The introduction of new characteristics to some synthetic polymers was achieved through the γ-radiation-induced graft copolymerization of methyl methacrylate onto low density polyethylene films (in the presence of aniline as inhibitor) for the preparation of grafted films. The influence of the reaction conditions on the grafting yield, such as the irradiation dose and the inhibitor was investigated. An alkaline treatment was carried out for the prepared graft copolymer to improve its ion-exchange property. The grafted and treated membranes were characterized to determine the structural changes with Fourier transform infrared spectroscopy. The electrical properties of the graft copolymer were studied. Improvements in the electrical conductivity with grafting were observed. The KOH treated films possessed higher electrical conductivity than the untreated ones.
