| 摘 要： | 双马来酰亚胺能改进硅橡胶在空气或氧气中的热稳定性。热老化试验和热降解动力学分析表明,其机理可能是双马来酰亚胺能优先与氧作用,避免了硅橡胶链上侧甲基被氧化,减轻了交联密度的提高,从而提高了硅橡胶的热稳定性。

| Abstract: | Dimaleimides can improve the thermal stability of silicone rubber in are or oxygen. The results of heat ageing test and kinitic analysis of TG showed that the mechanism may be related to the precedent reaction of dimaleimides with oxygen. So the oxidation of methyl group and the increase of crosslinking density of silicone rubber could be avoided. |
