摘要
本试验利用傅里叶变换红外光谱仪考察了２，４－二氨基－１，５－二甲硫基（ＤＡＤＭＴ）和Ｎ，Ｎ－二（２－羟乙基）苯胺（ｌｓｏｎｏｌ）分别与聚酯型预聚物和了羟型预聚物固化反应过程，求出相应体系的反应动力学常数和表观活化能。并对扩散控制阶段的反应过程进行了分析和讨论。
The reactions of DADMT with and isonol with prepolymer of polyester-TDI and hyolroxy-terminated polybutadiene--TDI were respectively investigated by Fourier transform infrared. The correspoding kinetics constants and activation energies were obtained. Then kinetics constsnt in diffussion--controlled stage were analysized and discussed.
