摘　　要：在潘祖仁教授主编的《高分子化学》(第五版)教材中:对于非密闭系统,在推导可逆平衡线形缩聚动力学方程时,由于设定反应物起始浓度为1,而在公式整理过程中忽略了反应物起始浓度所带的单位,造成利用动力学方程进一步推导得到的聚合度计算公式中,存在参数单位不一致的情况。为了解决这一问题,本文通过重新设定部分排水系统的反应物及生成物浓度,并在公式推导过程中保留浓度参数所带单位,解决了教材中聚合度公式存在的不合理之处。最后,将所推导的公式用于实际的解题运算中,进一步验证了公式的准确性。In the textbook of Polymer Chemistry(5 th Edition)edited by Prof.Pan Zuren,for the unsealed system,the initial concentration of reactant was set as 1,when deriving the kinetic equation of reversible equilibrium linear polycondensation.Then,as the unit of initial concentration of reactant was ignored in the process of equation arrangement,inconsistence of parameters unit existed in the formula of polymerization degree,which was derived from kinetic equation.In order to solve the irrationality of the polymerization degree formula,the concentrations of reactants and products were set and retained in the equation arrangement process.Finally,by solving practical problems correctly,the accuracy the formula polymerization degree derived in this paper was proved.
