The equilibrium swelling behavior of heterogeneous systems consisting of a consisting of a continuous network phase and a dispersed lamellar, spherical, or cylindrical phase is described using a thermodynamic model. The case of swelling of both phases but to different extents is described. The equilibrium volume fractions of each phase as well as the stresses at equilibrium are predicted as functions of the polymer interaction parameter, X , the modulus, G, and the geometric character of the networks.
