A model of continuous-site distribution for gas sorption in glassy polymers is examined with sorption data of CO 2 and Ar in polycarbonate. A procedure is presented for determining from a measured isotherm the number of sorption sites in a polymer, an important parameter that previously had to be as

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

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.

Gas sorption and permeation of physically treated glassy polymeric membranes is studied from the viewpoint of the transport mechanism and the control of microvoids in the membrane. Physical treatments, such as sub-T g annealing, thermal quenching, and CO 2 pressure conditioning were found to be effe

## Abstract The purpose of this article is to elucidate the effect of integral sorption of moisture on gas permeation in glassy hydrophilic polymers. The oxygen and the simultaneous moisture sorption into various hydroxypropyl methylcellulose (HPMC) films were measured under a wide range of relativ
