摘　　要：研究了乙撑碳酸酯和乙烯撑碳酸酯 -甲基丙烯酸 -β-羟乙酯共聚物交联载体与正丁胺、乙醇胺和二乙醇胺之间的胺解反应动力学 .根据动力学曲线获得了乙撑碳酸酯与三种有机胺在不同反应条件下发生胺解反应的速率常数 .对聚合物载体与有机胺反应的产物进行了红外谱图分析和元素分析 ,并计算了每克聚合物载体固载有机胺的量 ,发现该类聚合物载体分子上的环碳酸酯基易于在温和条件下与胺基发生开环反应 。The kinetics of aminolysis reaction of ethylene carbonate and poly (vinylene carbonate 2 hydroxyethyl methacrylate) by ethanolamine, diethanolamine and butylamine was studied. The aminolysis reaction rate constants of ethylene carbonate by ethanolamine, diethanolamine and butylamine were obtained according to the kinetic curves under different reaction conditions. The products of aminolysis reaction between polymer and amine were studied by IR spectra and elemental analysis. The cyclic carbonate could react with amino group under moderate condition.$$$$
