The dependence ofwater-diffusion in polyamide 6 on water concentration can be described by the equation D(c)=D(O) + p2. The mean value D correlates with the diffusion coefficient defined by Fick's law and depends exponentially on temperature with the activation energy E, = 0.49 eV. The diffusion pro
