Determination of solubility coefficients and sorption isotherms of gases in polymers by means of isothermal desorption with a chromatographic detection

A new method is developed for determining the solubility coefficients of gases in polymers that combines the advantages of the static and dynamic approaches to sorption estimation and allows us to determine the equilibrium characteristics of sorption for small quantities of samples (0.1–0.2 g) and l...
