摘要：按照溶解度参数的新定义 ,建立了一个两维溶解度参数体系 ,它由物理和化学两个溶解度参数分量构成 ,这两个分量的拆分借鉴了Wiehe新近提出的原则 .对每一种聚合物在不同液体中的溶解度实验数据作图表明 ,所有溶剂几乎都聚集在溶解度参数图的某一区域内 ,这个区域可用一椭圆表示 .通过一个简单的加和规则 ,它能用来满意地预测混合溶剂的溶解能力 ,为聚合物选择溶剂提供了重要的依据 .广泛的检验表明 。
A new two-dimensional solubility parameter consisted of the physical and chemical (solubility parameter) components has been established. The method proposed by Wiehe is used as a reference to divide the two components. From the profile of solubility data, it can be seen that all solvents are almost located within some area of solubility parameter diagram for every polymer. This area can be expressed by an ellipse, which provides an important basis for the selection of polymer solvents. Using a simple adding rule, it can be satisfactorily used to predict the solvency of mixing solvents. The results of extensive testing show that the new two-dimensional solubility parameter is more reliable than Hansen's three-dimensional solubility parameter for the selection of polymer solvents.
