## Abstract In order to verify precisely the applicability and reasonableness of the timeβhumidity superposition method to hydrophilic crystalline polymers, stress relaxation measurements were carried out with films of polyvinyl alcohol and nylon 6 by means of a table model Instron Tensile Tester e
A molecular model for diffusion of gases and vapors of low-molecular weight at low pressures through semicrystalline polymer films is developed. The formulation of a molecular model allows us to consider the temperature dependence a t constant penetrant concentration of the effective diffusion coeff
