Original Measurements
Variables:
Ambient temperature: 293 - 313 K
Pressure: 0 - 93 kPa
Prepared by:
Method/Apparatus/Procedure:
A McBain balance with a quartz spring was used in sorption measurement.
Source and Purity of Materials:
- PVTMS synthesized in the presence of BuLi had Mw = 608,000 and Mn = 416,000. All the gases were chromatographically pure.
Estimated Errors:
Mass concentration (m/v) (1): 10%.
Experimental Values:
Solubility coefficients S/(cm3(STP)/cm3 atm) at 298 K and enthalpies of sorption ΔH kcal/mol
