摘　　要：采用非等温动态示差扫描量热法(DSC)和热失重分析法(TGA)研究了N,N,N',N'-四缩水甘油胺-4,4'-双[4-(4-氨基苯氧基)苯基]丙烷/甲基纳迪克酸酐/2-乙基-4-甲基咪唑(TGBAPP/MNA/EMI-24)体系的固化反应过程及固化物的热稳定性。由Kissinger方程和Ozawa方程求得该体系固化反应的表观活化能分别为65.4 kJ/mol和69.0 kJ/mol;由Crane方程求得固化反应近似为一级反应;TGBAPP/MNA/EMI-24体系固化物具有良好的耐热性能,其Tg为226℃,5%,15%和30%的热失重温度分别为312℃,344℃和397℃。The curing reaction of N, N, N＇, N＇ - tetraglycidyl -4, 4＇ - bis（4 - （4 - amino phenyl） phenyl） pro- pane / methyl nadic anhydride/2 - ethyl - 4 - methylimidazole （ TGBAPP/MNA/EMI - 24 ） system and thermal sta- bility of cured product were investigated by dynamic non - isothermal differential scanning calorimetry （DSC） and thermogravimetric analysis （TGA）. The curing apparent activation energy were 65.4 k J/tool and 69.0 kJ/mol cal- culated by the Kissinger and Ozawa method, respectively. The curing reaction was approximately first order reaction obtained by the Crane equation. The cured product of TGBAPP/MNA/EMI -24 system showed good heat resist- ance and the Ts was 226 ℃ , 5% , 15% and 30% mass loss temperature of cured resin were 312 ℃ , 344℃ and 397℃, respectively.
