Variables:
Ambient temperature: 293 - 308 K
Pressure: 6.6 - 52.5 kPa
Prepared by:
Method/Apparatus/Procedure:
Cahn electrobalance was used to measure sorption.
Source and Purity of Materials:
- PBLG: prepared by benzylation of L-glutamic acid with subsequent polymerization. The degree of polymerization was always 1200, except the sample cast from ethylene dichloride where it was equal to 550. Heat treatment was performed at 413 K for several hours.
Estimated Errors:
Ambient temperature: Precision in T: ±0.5 K.
Mass concentration (m/v) (1): Weight determination accuracy: ±10 mg for 50-100 mg samples. Precision in: T: ±0.5 K.
