Abstract The radiation chemistry of methacrylonitrile-styrene copolymers which were γ-irradiated at -196°C with different radiation doses has been investigated by ESR spectroscopy. The calculated G(R.) values show that the copolymers display significant radiation protection effects. The mechanism of these effects has been discussed. In addition, annealing experiments for a copolymer sample show that there are different stages of radical decay, which reflect the stabilities of different kinds of radical species and the mobility of the chain segments in the copolymer.
