The purpose of this paper is to take into account the derivative by moisture content of polymer volume in order to establish a diffusion law within the so‐called “thermodynamical approach” for a polymer material which experiences a hygro‐mechanical load. In this study, the specific case corresponding to the existence of unsymmetrical hygroscopic boundary conditions was investigated.
