Аннотация

Phase transitions in the PE-PVA and PE-PMMA systems were studied in the static state and upon application of a shear stress field using the methods of cloud points, viscometry, polarization microscopy, and DSC. The application of shear stress weakens the interaction between the components, as manifested by an increase of the temperature of crystalline phase separation. It was shown that, for the PE-PVA system. the shapes of the boundary curves change. The concentration dependences of the orientational entropy and the parameter of interaction between the components of the polymer-polymer systems perturbed by the mechanical field were calculated.
