Abstract
By the cloud point and static sorption methods, phase diagrams are constructed and the concentration and temperature dependences of the Gibbs free energy of mixing and the interaction parameter are determined under static conditions and in a shear field for the poly(methyl methacrylate)-polystyrene-ethyl acetate, polystyrene-polybutadiene-toluene, polystyrene-polybutadiene, poly(methyl methacrylate)-polystyrene, poly(methyl methacrylate)-ethyl acetate, and polystyrene-ethyl acetate systems. Phase separation in the systems both under heating and cooling, as well as coexistence of three phases, is observed in the polystyrene-poly(methyl methacrylate)-ethyl acetate system. Deformation changes the phase separation temperature by 30–40 K.
