Method/Apparatus/Procedure:
A modified McBain balance technique was used to measure the solubility of sulfur dioxide in the polymer.
Source and Purity of Materials:
- PC ("Lexan") $\rho = \pu{1.119 g mL-1}$, provided by General Electric Co. (USA). $M_{\rm{w}}$ = 45,000; $T_{\rm{g}}$ = 422 K. Sulfur dioxide of 99.95% purity was used.
Estimated Errors:
Ambient temperature: δT/K = ±0.5 K.
Components:
- Copoly(pyromellitic dianhydride-oxydianiline) (PMDA-ODA), [25036-53-7] NIST WebBook
- Polycarbonate (PC), $\ce{ (C16H18O5)n }$; [25037-45-0] NIST WebBook
