Abstract: The results of the interphase diffusion in the system hydroxyethylcellulose film-water as a function of solid polymer compression are discussed. The experimental technique is briefly described and the possible swelling mechanism is proposed. The pressure dependence of the diffusion coefficient is divided into two regions: the one of elastic and the other of permanent polymer chain deformation. The change to permanent deformation is controlled by deformation time or by values of the external pressure.
