测量了聚乙烯（ＰＥ）、聚氯乙烯（ＰＶＣ）、乙丙橡胶（ＥＰＲ）和氯磺化聚乙烯（ＣＳＭ）等线缆绝缘材料经辐照后在热老化过程中的Ｏ２消耗量与ＣＯ２生成量，发现ＣＯ２生成量随Ｏ２消耗量呈线性增加。计算了氧化降解反应的表观活化能，探讨了氧化降解的反应机理。
The oxygen consumption during thermal aging of irradiated cable insulation materials such as polyethylene (PE), polyvinyl chloride (PVC), ethylene-propylene rubber (EPR) and chlorosulfonated polyethylene (CSM) The amount of CO2 generation was found to increase linearly with O2 consumption. The apparent activation energy of the oxidative degradation reaction was calculated and the reaction mechanism of oxidative degradation was discussed.
