The effects of gamma radiation on pristine poly(vinyl chloride) in the presence of the antirads 2-vinylnaphthalene and 4-vinylbiphenyl have been studied. External protection derived from the addition of antirads at 3 and 5% wt concentration in the PVC film and internal protection from grafted antitrades was evaluated. The grafted antirads were obtained through irradiation with a Co-60 gamma source at a dose rate of 10.5 kGy h(-1). Doses ranged from 10 to 40 kGy. Radiation resistance of the modified and pristine PVC (PVC-g-antirads and blends) was evaluated in the range of 600-3000 kGy at a dose rate of 10 kGy h(-1). The radiation resistance was characterized from crosslinking measurement, infrared spectroscopy, thermogravimetric analysis, and differential scanning calorimetry.
