摘　　要：传统的二元醇与二元酸缩聚反应动力学计算中,常常忽略体系体积的变化对动力学参数的影响。本文考虑了反应体系体积变化的影响,推导出以体积摩尔浓度表示的总包动力学方程,得到了相应的动力学参数。结果表明,该缩聚反应体系应该考虑体积变化的影响。The effects of system volume change on kinetic parameters were usually neglected during the kinetics calculation of traditional study on polycondensation reaction between diols and diacids.In this paper,the general kinetic equation was derived expressed in molar concentration,and the corresponding kinetic parameters were obtained under the consideration of the volume change of reaction system.The results showed that the effects of the volume change should be taken into account in polycondensation.
