A general expression for the diffusion flux in a binary polymer-solvent system is presented. It is shown that the current approach is capable of sorting out various complex diffusion phenomena. In particular, the dependence of the diffusion flux on a gradient of a generalized chemical potential emerges naturally by considering the limit of “weak equilibrium”.
