用热重分析法测定了PVC及不同氯化锌用量的PVC脱氢氯化过程的动力学参数。并与不同温度下降解的含ZnCh PVC膜的紫外可见光谱分析结果进行了比较。表观活化能（Ea）随zncl2用量的增加而减小，与前人的研究结果比较，得到的结果是合理的。阐述了氯化锌对聚氯乙烯二氯化反应的催化作用。
The kinetic parameters of dehydrochlorination (DHCL) process of PVC and PVC mixed with different amount of ZnCl2have been determined by using thermogravimetric analysis. These values have been compared with those obtained by using UV-visible spectroscopic analysis of PVC film containing ZnCh degraded at different temperatures. The values of apparent activation energy (Ea) decreases with the increase of the amount of ZnCl2and the values obtained in the present work are in reasonable comparison with previous works. The catalytic effect of ZnCl2on PVC DHCL process is explained here.
