摘　　要：回顾了近年来有关各种聚砜材料在电子、γ和重离子辐照下降解机理、气态产物及其辐射化学产额、性能和结构变化的相关研究成果,并对相关研究进展进行了综合分析,有助于理解各类聚砜材料在辐射下的降解行为。The effects of radiation degradation on the properties and structure of various polysulfone under various irradiations, such as electronic beam irradiation, γ-irradiation and heavy ion irradiation have been reviewed and discussed in this paper. It has been shown that the previous studies are mainly concerned with degradation mechanism, the kinds of gas products, radiation chemical yields of degraded polysulfone and the relationship between properties and constructure of irradiated polysulfone. However the basic studies were insufficient to estimate the applied lifetime of polysulfones under irradiation situation. And the achievements are helpful for understanding the degradation behavior of various polysulfones under irradiation.
