Experimental Support of “Dual Sorption” in Glassy Polymers

  • Paul J. Fenelon
Part of the Polymer Science and Technology book series (PST, volume 6)


To explain equilibrium sorption isotherms for some gases in glassy polymers, Michaels, Vieth (1,2,3) postulated that sorption was occurring by two distinct modes. This postulate has since become known as the “Dual Sorption Model”. Vieth (2,3) achieved a mathematical description of transient sorption behavior by further postulating that one of the sorption modes immobilizes the gas molecules while the other gives rise to the driving force for transport.
