Abstract
IR absorption spectroscopy is a suitable technique to study degradation and damaging effects, induced by gamma radiation, on polymeric materials. The most important effects, crosslinking and oxidative degradation, influence IR spectra which are very sensitive to oxidation. Since very few attempts have been made to apply IR spectroscopy to quantitatively study the effects of the radiation degradation of rubbers in hostile environments, ENEA (the Italian Agency for New Technology, Energy and the Environment) made a preliminary study on radiation induced oxidative degradation of an ethylene-propylene copolymer crosslinked by dicumilperoxide and loaded with 1 mol% antioxidant. The IR spectra were obtained with a Perkin Elmer FTIR spectrophotometer. The spectra showed that exposure of the samples to gamma doses resulted in noticeable changes in the absorption bands. In analyzing irradiation effects ascribed to the stretching of C=O groups produced by the oxidation process, no variations in the mechanical properties of the samples were found although there were distinct signs of chemical alteration.
