P-CPHC狀態方程式於聚合物溶液之汽液相平衡計算

本研究在於驗證P-CPHC狀態方程式應用於聚合物溶液關聯計算的適用性。從文獻中收集到80組的聚合物溶液之汽液相平衡數據，整理後共有17個溶劑、35個不同平均分子量的聚合物。35個聚合物經由一點的密度數據分別求取其P-CPHC狀態方程式之待定物質參數。汽液相平衡數據經最適化關聯計算，求取雙成分交互作用參數和，總體的ARD％在12以下。由計算結果顯示，雙成分交互作用參數的絕對值會隨著溫度的上升而減少，隨著聚合物分子量的增加而增加，則未呈現同一規則之溫度效應。P-CPHC+Flory-Huggins模式於聚合物溶液有不錯的計算結果，其交互作用參數χ值隨著聚合物分子量的增加而增加。

In this research, we use the Polymer CPHC equation of state to demonstrate the applicability by correlating calculation of polymer solutions. We collect 80 sets vapor-liquid phase equilibrium data of polymer solution in literatures, that contain 17 solvents and 35 different average molecular weight of polymers. The parameter of Polymer CPHC equation of state can be estimated from a single density datum of polymers. The optimal values of the binary interaction parameters and are determined from these vapor-liquid phase equilibrium data, and the grand percentage of an average absolute deviation ( ARD％) below 12. Analyzing the calculating data, the absolute value of binary interaction parameters decreases with increasing temperature, and increases with increasing molecular weight of polymers, not depend on temperature effects. P-CPHC+Flory-Huggins model in polymer solutions have excellent result, and the binary interaction parameter χ value increases with increasing molecular weight of polymers.
