采用原位傅里叶红外光谱法（ FTIR）研究了 AlH3／聚叠氮缩水甘油醚（ GAP）混合体系的热解特性。结果表明：AlH3在100℃开始分解，180℃达最大分解速率，250℃左右分解完全；GAP在200℃左右叠氮基开始裂解，并形成亚胺中间体，主链的完全解聚相对滞后；AlH3改变了 GAP的分解历程，AlH3／GAP在170℃开始分解，而且在分解过程中没有出现 C  N、C  O 等不饱和键，推测是由于 AlH3具有较强的还原性。

The thermal decomposition of AlH3,glycidyl azide polymer(GAP)and AlH3/ GAP mixed system were studied by in-situ thermolysis-fourier transform infrared spectroscopy(FTIR)coupling techniques. Results show that AlH3 begins to decompose when temperature raises to 100 ℃ and the decomposition rate reaches the maximum at 180 ℃ . The azide group of GAP begins to cleavage to imine intermediate at about 200 ℃. The main chain of GAP completely depolymerization is lagging behind. The decomposition process of GAP is changed by AlH3 . AlH3/GAP system loses mass when temperature raise to 170 ℃,and during the decomposition of AlH3/GAP,Such unsaturated bonds as CN and CO are not observed. The possible reason is the strong reduction of AlH3 .
