Ma. Krykin et al., GAS SORPTION AND DIFFUSION-PROCESSES IN POLYMER MATRICES AT HIGH-PRESSURES, Journal of polymer science. Part B, Polymer physics, 35(9), 1997, pp. 1339-1348
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.
