Method/Apparatus/Procedure:
The apparatus and procedure for measuring sorption isotherms were described in [1].
Source and Purity of Materials:
- The commercial polysulfone samples Torayslon-PS (Toray Co. Ltd.) and P-1700 (Union Carbide) were used. P-1700 had $T_{\rm{g}}$ = 459 K. A dense PSF (P-1700) membrane was prepared by casting a mixed solution of 25.5% PSF, 55.5% N,N-dimethylacetamide, and 19.0% acetone by weight. Purity of $\ce{CO2}$ not specified.
