Abstract
A theoretical approach has been developed to describe the processes of gases diffusion and sorption in rubbery and glassy polymers. Various models (Flory-Huggins, dual-mode sorption, gas-polymer-matrix) used fo r interpreting the sorption-diffusion experiments are discussed within this approach framework. Experimental data on carbon dioxide sorption in glassy and rubbery polymers have been considered using the propose d approach. The comparison of the experimental and theoretical data ha s permitted to make the conclusion on the developed concepts adequacy. (C) 1997 John Wiley & Sons, Inc.
