Method/Apparatus/Procedure:
Gas sorption measurements were performed using a Cahn RG microbalance. The sorption apparatus and procedure are discussed in [1].
Source and Purity of Materials:
- Emulsion polymerized PS (B. F. Goodrich Co R/D center) had $M_{\rm{n}}$ = 440 000 and $T_{\rm{g}}$ = 381 K.
Instrument grade propane was 99.99% pure.
