摘　　要：以含烯丙基醚的双马来酰亚胺预聚体(AE-BMI)作为苯并噁嗪(BOZ)的改性剂,采用非等温差示扫描量热(DSC)法、Kissinger法、Crane法和β-T(升温速率-温度)外推法研究了AE-BMI/BOZ体系的固化动力学过程。结果表明:BOZ体系的凝胶温度为174.86℃、固化温度为210.95℃和后处理温度为222.44℃,AE-BMI/BOZ体系的凝胶温度为114.84℃、固化温度为199.75℃和后处理温度为227.64℃;两者的反应活化能分别为89.03、69.97 kJ/mol,反应级数分别为0.83、0.79。With AE-BMI prepolymer（l^ismaleinlide with allyl ether） as modifier of benzoxazine（BOZ）,tile ~＇uring kinetics process of AE-BMI/BOZ system was investigated by non-isothermal DSC（differential scanning calorimetry）, Kissinger, Crane and fl-T（heating speed-temperature） extrapolation methods. The restdls showed that the gelation te,nperature,curing temperature and post-processing temperature for BOZ system were 174.86,210.95,222.44 ℃ respectively,and the gelation temperature,curing temperature and post-processing temperature tor AE-BMI/BOZ system were 114.84,199.75,227.64 ℃ respectively. The reaction activation energies of BOZ system or AE-BMI/BOZ system were 89.03 k J/tool or 69.97 kJ/mol, and reaction orders of BOZ system or AE-BMI/BOZ system were 0.83 or 0.79.
