摘　　要：采用刚性脂环胺异佛尔酮二胺(IPDA)和碳酸丙烯酯(PC)作为原料,合成了一种脂环基非异氰酸酯聚氨酯(IPDC),通过红外光谱、核磁共振对其结构进行了表征。考察了合成反应的影响因素,结果表明,温度升高体系转化率增加,并研究了IPDA/PC反应体系的动力学方程,得到体系动力学方程的反应级数为2.201,表观活化能为35.90 kJ/mol,指前因子为5.790 min-1。The non-isocyanate polyurethane IPDC was synthesized by rigid alicyclic amine isophorone diamine(IPDA) and propylene carbonate(PC). The structure was characterized by FTIR and 1 HNMR. The synthesis kinetics of isophorone diamine and propylene carbonate has been studied. The results showed that the reaction order of IPDA/PC system was 2.201, the apparent activation energy was 35.90 kJ/mol, and the pre-exponential factor was 5.790 min-1. When the reaction temperature was 100 °C, the conversion rate of the system could reach 86.2%.
