## Abstract The description of the sorption mechanism of gases in glassy in glassy polymers is of importance for membrane‐based 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
Sorption isotherms of glassy polymers are concave to the pressure axis, and the absolute sorption levels are almost an order of magnitude higher than that of rubbery polymers on the relatively low-pressure side. There are several models to interpret this behavior, and the dual sorption model is the
