| 中文摘要: |
| 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。 |
| 英文摘要: |
| The heat-oxidative aging and heat aging properties of epoxidized styrene-isoprene-styrene（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，carboxylic 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. |
