| Abstract: | 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 the model are compared with general experimental observations. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 71: 1431–1440, 1999 |
