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
## Abstract The description of the sorption mechanism of gases in glassy in glassy polymers is of importance for membraneβbased gas separation processes as well as for packaging applications. Dual mode theory, postulating a Henry and Langmuir process to occur and leading to an equation with three a
