在目前聚合物溶液分子热力学模型基础上，通过分析比较得出几个较好模型，然后利用实验数据优化拟合，筛选出Ｇｒｏｕｐ－ＣｏｎｔｒｉｂｕｔｉｏｎＭｏｔｈｏｄｆｏｒｅｓｔｉｍａｔｉｏｎｏｆｔｈｅｔａｔｅｍｐｅｒａｔｕｒｅａｎｄｐｈａｓｅＥｑｕｉｌｉｂｒｉａｏｆｐｏｌｙｍｅｒｓｏｌｕｔｉｏｎ（简称ＧＣＭ模型）作为今后考察、改进和模型参数基团化的首选模型，并进一步用ＧＣＭ模型关联了常温下笔者所测的汽液平衡实验数据以及文献中一些系统的汽液平衡数据，得到了可基团化的能量相互作用模型参数。关联结果表明ＧＣＭ模型对种类广泛的系统的汽液平衡是适用的。
Based on the current molecular thermodynamic model of polymer solution, several good models are obtained through analysis and comparison, and then the Group-Contribution Method for judging the accuracy and the method of Equilibria of Polymersolution (GCM model) is selected as the future investigation, improvement and model parameter group And the GCM model is further used to correlate the vapor-liquid equilibrium data measured by the author at room temperature and the vapor-liquid equilibrium data of some systems in the literature to obtain the parameters of the model for energy interaction that can be reorganized. The correlation results show that the GCM model is suitable for a wide range of systems in terms of vapor-liquid equilibrium.
