Method/Apparatus/Procedure:
The method of 'interval' sorption was used. Pressure decrease due to sorption in a closed system of known volume was measured with a pressure transducer. Polymer samples were put between two discs of sintered glass. No correction for the swelling of the sample was introduced.
Source and Purity of Materials:
- PS had $M_{\rm{w}}$ = 500 000.
Purity of methane was >99.0%.
Estimated Errors:
Ambient temperature: ±0.02 K.
Mass concentration (m/v) (1): < 5%.
Pressure: ±0.5 atm.
Components:
- Methane, $\ce{ CH4 }$; [74-82-8] NIST WebBook
- Polystyrene (PS), $\ce{ (C8H8)n }$; [9003-53-6] NIST WebBook
