摘要

缩聚反应是《高分子化学》的重点内容之一，目前国内教材中主要以线形缩聚反应为主线，介绍缩聚反应的基本规律与特征。因此，典型的线形缩聚产物聚己二酸乙二醇酯（PEA）的合成动力学研究成为与课程配套的《高分子化学实验》课程的主要内容。四川大学开设的《高分子化学实验》课程中就包含熔融缩聚反应动力学研究，在外加酸催化条件下研究线形聚酯PEA合成过程中的熔融缩聚反应动力学。本文针对实验数据处理过程中，变温情况下求反应速率常数

与反应活化能

时的具体处理方法进行了分析，针对存在的问题提出了改进措施，并对比了改进前后实验结果的差异。

Abstract

Polycondensation is one of the fundamental components of "Polymer Chemistry"

and its basic rules and characteristics are introduced mainly by linear polycondensation in domestic textbooks. Therefore

the synthesis kinetics of a typical linear polycondensation product

Polyethylene glycol adipate (PEA)

becomes a main content of "Polymer Chemistry Experiment". Melt polycondensation kinetics experiment is included in the course of "Polymer Chemistry Experiment" of Sichuan University

which studies on the kinetics of melt polycondensation in the synthesis of linear polyester PEA under the condition of acid catalysis. In this paper

some problems in data processing havebeenanalyzed

a measure of improvement is put forward to solve the problems. Two different methods are used to calculate the reaction rate constant k and the activation energy E

under the condition of changing temperature. Finally

the differences between the experiment results are compared before and after the improvement.
