摘　　要：用傅里叶变换红外光谱(FT-IR)对聚叠氮缩水甘油醚(GAP)-异佛尔酮二异氰酸酯(IPDI)预聚物以及-NCO基团封端的GAP预聚物/硝化棉(NC)体系固化反应动力学进行了研究。结果表明,两种体系的固化速率均随着温度的升高而加快;当固化催化剂T12的质量分数为0.025%时,两种体系固化反应的表观活化能分别为64.88kJ/mol和111.19kJ/mol,且均表现为二级动力学反应。The glycidyl azide polymer（GAP） /isophorone diisocyanate （IPDI） system and GAP-IPDI/prepolymer/ nitrocellose（NC） system were prepared. Their curing reaction kinetics was studied by FT-IR. The experimental results show that the reaction rates of the two systems increase with an increase in temperature. When the content of the curing catalyst T12 is 0. 025%, the apparent activation energy of the curing reaction for the two systems are 64.88 kJ/mol and 111.19 kJ/mol, respectively, and the reaction appeares as second-order kinetic reaction.
