Phase equilibria for polymer systems such as (1) vapor-liquid equilibria, (2) liquid-liquid equilibria, (3) aqueous two-phase system, and (4) volume-phase transition of polymeric gel were reviewed. The authors first described solubilities of gases and vapors in molten polymers and showed that the UNIFAC-FV model is successful to predict the vapor-liquid equilibria. Furthermore, liquid-liquid equilibria of polymer-hydrocarbon solutions were discussed and it was shown that the UNIFAC-FV model with a modification is also useful to correlate the liquid-liquid equilibria. And the liquid-liquid equilibria of aqueous two-phase system and the partition of biomolecules were presented and the Flory-Huggins equation with a modification is found to be successful to correlate these phase equilibria. Finally, the volume-phase transition of polymeric gel and the concentrations between inside and outside the gels were described. The Flory-Huggins equation coupled with the rubber elasticity equation was found to be helpful to correlate these phase equilibria.
