In the scientific literature swelling and shrinking of polymer gels are often considered as diffusion process. According to this idea the kinetics of volume change is determined by the diffusion coefficient of the solvent. In this paper we provide theoretical and experimental evidences that the swelling of anisometrical gel can't be understood an the basis of a pure diffusion mechanism. The shear modulus plays an important role: it keeps the system in shape due to coupling of any change in different direction. As a result of this, the geometry of the gel plays an important role. Change in the dimension in the directions of the longer dimension is larger than that of the shorter dimension.
