摘　　要： 研究环氧化苯乙烯-异戊二烯-苯乙烯(ESIS)的热氧老化及热老化性能。结果表明,ESIS在热氧老化及热老化过程中的组成变化相似,C C双键、环氧基、甲基、亚甲基和次甲基等不同程度地减少,同时生成醛、酮、醚和羧酸等,C C双键的稳定性好于环氧基;与SIS相比,ESIS的耐热性能稍有提高。 The heat-oxidative aging and heat aging properties of epoxidized styrene-isoprenestyrene（ESIS） were investigated. The results showed that the change of components of ESIS during heat-oxidative aging and heat aging were similar ; the amount of C=C ,epoxy group,methyl,methylene and methine reduced, but at different level, and the products were aldehydes, ketones, aethers, car boxylic acids;the stability of C=C was better than that of epoxy groups;the heat resistance of ESIS was a little better than that of ESIS.
