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.
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。
