摘要

采用预辐射方式将NIPAAm接枝到硅橡胶上，结果表明：接枝反应是由样品在空气中辐照生成的过氧化物（主要是氢过氧化物）引发的，并且仅在较高温度下接枝才能进行。研究了过氧化物的产生和分解，计算出过氧化物分解的活化能为27.2kJ/mol。通过对接枝反应动力学的研究表明，接枝反应的活化能较低，约54.7kJ/mol。讨论了接枝反应机理。

Abstract

Pre-irradiation grafting of poly NIPAAm on silicone rubber was completed successfully. It was found that the graft reaction could be done just at higher temperature and induced by peroxides (mainly hydrogen peroxides) produced during irradiation of samples in air. Production and decomposition of the peroxides were investigated. The active energy of peroxides decomposition equals to 27.2 kJ/mol. The study of grafting kinetics showed that the graft reaction is easy to occur at higher temperature because of the active energy of graft reaction was low,near to 54.7kJ/mol. And the grafting mechanism was discussed deeply.
