Method/Apparatus/Procedure:
Sorption was studied using a McBain balance with quartz spring. The procedure has been described in [1].
Source and Purity of Materials:
- $\ce{SO2}$: traces of air were removed from the gas prior to use.
PVTMS films: recast after dissolving gas separation PVTMS membrane (NPO Plastmassy) is methylbenzene.
Estimated Errors:
Ambient temperature: No information given.
