Abstract
The application of pressure to solutions of polyethylene oxide in water causes phase separation through spinodal decomposition similar to that observed when the temperature is raised above the lower critical solution temperature. This phase separation pressure is dependent on molecular weight but independent of concentration. Viscosity measurements indicate a continuous decrease in the radius of gyration from good to theta solvent conditions as pressure is increased. This pressure-induced loss of solvent quality is a result of the loss of the ability of water to form hydrogen bonds at high pressure and the resulting changes in hydrophobic interactions.
