| 摘 要： | 本文对叔胺催化剂体系中低温溶液法合成聚芳酯的反应动力学进行了研究,建立了缩聚反应的数学模型。通过求解该数学模型,获得缩聚反应中反应物浓度与时间之间的关系式,所得理论值与实验值吻合得很好。与此同时,还计算了反应速率常数和活化能,并考虑到影响速率常数的因素,得到较有价值的结果。

| Abstract: | In this paper,the reaction kinetics of low-temperature solution polycondensation in tertiary amine catalystic system is studied,and the mathematical model for the kinetics of condensation polymerization is established.By use of the model,the theoretic relationship between reactant concentration and time is obtained.The experimental results are well fitted by the theoretic values calculated from the above model.Meanwhile reaction rate constant and activation energy are calculated,and the factors influenoing the reaction rate constant are discussed.Valuable results have been obtained. |
