Liquid-liquid equilibria for random copolymer of ethylene oxide plus propylene oxide plus salt plus water
Liquid-liquid equilibria of aqueous two-phase systems composed of aqueous solutions of random copolymer of ethylene oxide + propylene oxide and various salts were measured. The salts used were Na2SO4, K2HPO4, KH2PO4, and the mixture of K2HPO4 + KH2PO4. Tile effect of temperature on liquid-liquid equilibria is discussed.
