【摘要】 讨论了环氧化天然橡胶（ENR）的制备反应动力学。热分析研究表明，不同环氧化程度ENR的Tg值、热降解温度、热降解活化能均随环氧化程度的升高而增大。表明随着环氧化程度的提高，ENR在氮气中的热稳定性升高。更多还原

【Abstract】 The kinetics of ENR preparation was discussed. The thermal analyss showed that the Tg values, the thermaldegradation temperatures and thermal deqradation activation energy of ENR increase with extents of epoxidation (B). The re-sults indicate that the thermal stability of ENR increases with B.更多还原
