摘要：

Phase transitions in the poly(ethylene glycol)-poly(propylene glycol) and poly(ethylene oxide)-poly(vinyl acetate) systems in the static state and upon application of a shear stress field were studied using the methods of turbidity points, viscometry, polarization microscopy, and X-ray diffraction, The application of shear stress weakens the interaction between components, which is accompanied by an increase in the temperature of crystalline phase separation and is manifested by a change in the shapes of boundary curves. The concentration dependences of the parameter of interaction between components in the polymer systems perturbed by the mechanical field were calculated.
