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.
