A new theory is developed for integral sorption and desorption processes in glassy polymers. The theory can describe both case II diffusion and the classical case of Fickian diffusion. Predictions of the theory are compared with general experimental observations.
Anomalous sorption curves have often been observed for differential sorption experiments in glassy polymers. A model is proposed to describe this non-Fickian behavior. This model is based on the presence of interfacial resistance caused by slow rate processes at the phase boundary. Predictions of th
