Abstract. have developed'a framework We of thermodynamics hydrodynamics of and chemically crosslinked framework of thermodynamics is analogous to that of binary gels. Our fluid mixtures, except that the former includes a variable describing the deformation of the solid (network) of gels. -The< framework portion of the hydrodynamics is based on the theory of hydrodynamics of systems with broken symmetry and on the assumption of local equilibrium. Inthe framework there is no plastic flow of solid portions of gels, an that present assume we assumption which leads to the identification field with the displacements of the order-parameter of the material composini the §olid portion. We also investigated the properties of the symmetry Olisager coeffiiients fir this system with an emphasis ok the relation to the metric tensor the'defirmation of the solid portion of iels.
