Method/Apparatus/Procedure:
Sorption isotherms for gases in the polymer were obtained gravimetrically using a Cahn Model 2000 electrobalance. Details of this apparatus were described previously.
Source and Purity of Materials:
- Gas purity: $\ce{CO2}$ 99.99%, CH4 99.9%, $\ce{C2H6}$ 99.7%. PSF (Udel Polysulfone): Nissan Chemical Industries Ltd., $\rho^{25} = \pu{1.240 g mL-1}$ ('as received') and $\pu{1.238 g mL-1}$ (after $\ce{CO2}$ exposure), $T_{\rm{g}}$ = 455 K.
Estimated Errors:
Ambient temperature: No information given.
