Original Measurements
Variables:
Ambient temperature: 293 - 313 K
Pressure: 0.2 - 3.0 MPa
Prepared by:
Method/Apparatus/Procedure:
Equilibrium sorption was measured by the pressure decay method in the cell similar to that described in ref. (1). The pressure in the cell was continuously measured by a pressure transducer.
Source and Purity of Materials:
- PS films provided by Mitzubishi -Monsanto Chemical Co were studied.
