摘要：

In this work we have studied the effect of gamma radiation on poly (vinyl chloride). Radicals produced by irradiation were investigated by EPR measurements at room temperature and the formation of conjugated double bonds was probed by JJV-VIS absorbance measurements; samples were also submitted to infrared measurements to be analysed in terms of oxidation products.
