摘要：

The glassy polymer lattice sorption model (GPLSM) is a lattice-based activity coefficient model that has been developed for gas sorption in glassy polymers. The model recognizes the presence of holes on the lattice and determines how the number of holes changes by taking into account swelling due to penetrant gas molecules. The GPLSM equation has a composition-dependent energy term similar to that in the Flory-Huggins theory and an entropic term based on the mixing of gas molecules and holes. The utilization of sorptive dilation data for the determination of the number of holes gives a physically realistic interpretation of the local free volume in a glassy polymer. A good representation of the experimental data is obtained for the carbon dioxide- and methane-polycarbonate systems.
