Abstract:

用变温傅里叶变换红外光谱法研究了二月桂酸二丁基锡(T12)存在下GAP/HMDI、GAP/TDI和GAP/IPDI(此处GAP,HMDI,TDI和IPDI分别为聚叠氮缩水甘油醚,4,4′-二环己基甲烷基二异氰酸酯,甲苯二异氰酸酯和异佛尔酮二异氰酸酯)体系的反应动力学。结果表明,GAP与三种异氰酸酯(HMDI,TDI和IPDI)的反应为二级反应。它们的反应速率均随温度的升高而加快。GAP/HMDI、GAP/TDI和GAP/IPDI体系的反应活化能分别为15.49,12.27和22.46kJ·mol-1,显示三个体系的反应活性递减次序为GAP/TDI>GAP/HMDI>GAP/IPDI。
