摘要
改进了Ｐｏｕｃｈｌｙ提出的Ｆｌｏｒｙ－Ｈｕｇｇｉｎｓ半经验展开式，详细推导了相应的计算三元相图中双结点溶解度曲线（Ｂｉｎｏｄａｌ线）和亚稳均相极限线（Ｓｐｉｎｏｄａｌ线）的方程；计算了非溶剂和溶剂的相互作用参数ｇ（１２）、溶剂和醋酸纤维素的相互作用参数ｇ＿（２３）同时依浓度变化的三元相图。结果表明：新的Ｆｌｏｒｙ－Ｈｕｇｇｉｎｓ方程更具有普适性。
A new generalized form of the Flory-Huggins equation was suggested, in which the interaction parameters in the binary mixture should be kept as the concentration of the binary mixture in the ternary system.The new equationts for the calculation of Binodal and Spinodal curves in the ternary system were developed. The effect of a polymer/solvent interaction parameter concentration dependence in the new and old forms was discussed.The results showed that the new Flory-Huggins equation is a more generalized form. The ternary phase diagrams calculated in the new and old forms were obviously different.The ternary phase diagrams of CA-acetone-water and CA-dioxane-water approach to the results obtained from the measurements.
