聚苯乙烯在环己烷、甲基环己烷系统中的液液平衡　Ⅰ．雾点线和旋节线的实验测定

摘要: 建立了高分子溶液雾点线和旋节线的测定方法及其实验装置，测定了环己烷－聚苯乙烯（Ｍ＿ｗ＝１９００００；Ｍ＿ｗ／Ｍ＿ｎ＝１．０４）、甲基环己烷－聚苯乙烯（Ｍ＿ｗ＝３７９００；Ｍ＿ｗ／Ｍ＿ｎ＝１．０１）系统的雾点线和旋节线，经与文献数据比较，表明本方法及其装置是可行的。

Abstract: An experimental apparatus and corresponding methods were established for the determination of liquid-liquid equilibria of polymer solutions including cloud point curves and spinodals, Measurements are given for cloud point curves and spinodals for the systems of cyclohexane polystyrene(= 190 000;M_w/M_n=1. 04) and methylcyclohcxane polystyrene(=37 900;=1.01) .The results are compared with the literature da ta.Good agreements indicate the reliability of our experimental apparatus and methods.
