Variables:
Ambient temperature: 293.2 K
Pressure: 0 - 100 MPa
Prepared by:
Method/Apparatus/Procedure:
The conventional McBain sorption spring balance was used.
Source and Purity of Materials:
- The copolymer was prepared via oxidative copolycondensation of two monomers. The purity of product 99.9%, it had density 1.10 g/cm3 and Tg =483 K. All the gases had a purity >99.9%.
Estimated Errors:
Ambient temperature: ±0.1 K
Mass concentration (m/v) (1): 0.1 (compiler)
Pressure: ±0.2 kPa
