Abstract: Isotactic polypropylene (IPP) films were modified through radiation-induced grafting of N-vinyl-2-pyrrolidone (NVP) with the aim of preparing hydrogels. The radioactive isotope cobalt-60 was used as the source of gamma radiation. A plausible mechanism of grafting has been proposed. The grafting conditions were optimized with respect to monomer concentration, time, temperature and amount of solvents. The structures of grafted films were characterized by FTIR, AFM and SEM studies. IPP-g-NVP films were investigated for their swelling behaviour as a function of different pH solutions. The prepared grafted films can have potential applications in the fields of controlled drug delivery systems.
