以杂萘联苯聚芳醚腈为研究对象,分别采用多种良溶剂和不良溶剂进行浊度滴定实验,由KY ( Kumar and Yildirim )一阶算法对其产生的25个浊点数据进行最小体积闭包椭球拟合,从而确定椭球球心为三维溶解度参数(δd =17.50( MPa )1/2;δp =11.19( MPa)1/2;δH =10.96( MPa)1/2),椭球包围的区域为聚合物的溶解区域。采用THF作为鉴别溶剂,判定该拟合结果精确可靠。三维溶解度参数方法操作简便,计算简单、选用溶剂少,对聚合物溶剂的选择具有重要的指导意义。
以雜萘聯苯聚芳醚腈為研究對象,分彆採用多種良溶劑和不良溶劑進行濁度滴定實驗,由KY ( Kumar and Yildirim )一階算法對其產生的25箇濁點數據進行最小體積閉包橢毬擬閤,從而確定橢毬毬心為三維溶解度參數(δd =17.50( MPa )1/2;δp =11.19( MPa)1/2;δH =10.96( MPa)1/2),橢毬包圍的區域為聚閤物的溶解區域。採用THF作為鑒彆溶劑,判定該擬閤結果精確可靠。三維溶解度參數方法操作簡便,計算簡單、選用溶劑少,對聚閤物溶劑的選擇具有重要的指導意義。

The turbidimetric titration method in several good and poor solvents was used to calculate the three -dimensional solubility parameters of PPEN.The 25 cloud point data were mapped to three -dimensional space to search for a minimum volume ellipsoid for enclosing the sampling data using the KY ( Kumar and Yildirim ) algorithm.This optimized result of the ellipsoid center can be looked on as the three -dimensional solubility parameters of PPEN δd =17.50(MPa)1/2,δp =11.19(MPa)1/2, andδH =10.96(MPa)1/2.The result was tested by using THF solvent , showed to be accurate.The method was applicable to most kinds of polymers and had important directive significance to solve the problem in selection of polymer good solvents.
