- Аннотация: 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 low (<0.5 atm) partial pressures of the investigated gas. Sorption isotherms and solubility coefficients of nitrogen, oxygen, carbon dioxide, methane, ethane, and propane in polyvinyltrimethylsilane are obtained, and in poly[3,4-bis(trimethylsilyl)tricyclononene-7], polyhexafluoropropylene, and OHcontaining polyimide for the first time ever. It is shown that the sorption isotherms of gases for all of the gas–polymer systems in the investigated range of pressures are linear. The obtained solubility coefficients are compared to data for other polymers studied earlier.
