Method/Apparatus/Procedure:
Sorption isotherms were obtained by the pressure decay method. [1]. Conditioning at 23 atm for 60 h and degassing preceded the measurements.
Source and Purity of Materials:
- PVC: Samples were compression modeled at 450 K from a mixture of low molecular mass PVC resin and 3% of a stabilizer (Cincinnati Milacorn (TM-692)).
Estimated Errors:
Ambient temperature: No information given.
