摘要
用文献实验数据验证了己内酰胺水解聚合过程动力学模型，并对不同反应温度下聚合产物组成（己内酰胺单体浓度与转化率、环状二聚体及水的浓度、数均聚合度和多分散性指数）进行了模拟，得到己内酰胺水解聚合过程用先高温后低温的程序控温方法，与其工业生产实际控温方法完全一致。
A simulation model dealing with the kinetic behavior of the hydrolytic polymerization of ε\|caprolactam with monofunctional regulator was used to analyze the characteristic data of polymerization such as the concentration of caprolactam, cyclic dimer and water, caprolactam conversion, number\|average polymerization degree and polydispersity index. The calculated values based on the model were agreed with the literature data. The result showed that the controlled\|temperature method,i.e, higher at first and then lower temperature, for ε\|caprolactam hydrolytic polymerization agreed with the industrial nylon 6 polymerization process.
