Type of article: Article

Summary

Two aqueous phase systems are obtained when water is added to small amounts of incompatible but water-soluble polymers. This work aims to investigate theories and models for describing the thermodynamic behaviour of such complex systems. The first problem to face is the description of the substratum, namely the multi-component liquid-liquid equilibrium for water-polymer-polymer and water-polymer-electrolyte systems. It deals also with the description of the protein distribution among the two liquid phases. A new model was developed, and results are reported for systems containing polymers and systems containing electrolytes. Good results were obtained for polyethylene glycol-water and for water-electrolyte systems.
