SORPTION–DESORPTION OF WATER VAPOR BY LINEAR AMORPHOUS POLYMERS

The laws governing sorption–desorption of water vapor by microporous sorbents based on linear amorphous polymers (polystyrene, polyvinyl chloride, and polymethyl methacrylate) have been studied. A mathematical model of sorption–desorption hysteresis is presented. Based on the proposed model, it is shown that the sorption– desorption process is aff ected by the presence of free active centers of the polymer, which interact with water molecules.
