Abstract
The phase transitions in a poy(ethylene glycol) (PEG)-glycerol-water system were studied under Static conditions and on exposure to a shear field. It was discovered:that deformation results in an increase in the temperature o f the phase separation of the PEG Solutions. The concentration dependences of the interaction parameter of components and the second virial coefficien ts of the polymer-mixed solvent systems distorted bl the mechanical field w ere calculated in terms of the Flory-Huggins theory.
