摘　　要： 用动态差示扫描量热法和热重分析法研究了 PPE/EP体系的固化反应和热分解反应,结果表明,其固化反应热和最大放热峰的峰温均随着 PPE含量的增加而减小.PPE/EP体系的分解过程为一级反应;以 Kissinger最大失重速率法求得表观活化能为 184.54kJ/mol;以 Ozawa等失重百分率法求得 10%～ 30%的失重率下反应表观活化能在 208.09～ 188.64kJ/mol之间,频率因子 InA值在 34.55～ 31.05min- 1之间,表明 PPE/EP体系的热稳定性很高,这为覆铜板的制作提供了重要动力学参数. The curing reactions and thermal degradation reactions of poly （2, 6-dimethy-1, 4-phenylene ether） （PPE）/ epoxy （EP） systems were studied by dynamic differential scanning calorimeter and thermal-gravimeter. Curing reaction heat and themaximum peak temperature of PPE/ EP blends decreased with increase PPE content. The thermal degrade was first order reaction. The dynamic data had been analyzed using Kissinger peak maximum technique, giving an apparent global activation energy, E of 184.54kJ/mol. An isoconversional procedure developed by Ozawa was used, and E was decreased from 208.09 to 188.64kJ/mol with increase of the conver- sion from 10 to 30%. The frequency factor In A was also decreased from 34.55 to 31.05min^-1. For the fabrication process of copper clad laminate, some important kinetic parameters were provided.
