Original Measurements
Story, B. J.; Koros, W. J.; J. Appl. Polym. Sci. 42, 2613 (1991).
Variables:
Ambient temperature: 308 K
Pressure: 0 - 2.0 MPa (0 - 20 atm)
Prepared by:
Method/Apparatus/Procedure:
A standard pressure decay system (Ref. 1) was used in pure gas sorption. Mixed gas sorption experiments were performed using a special apparatus having additional chambers for preparation and chromatographic sampling of gas mixtures.
Source and Purity of Materials:
- CPPO: prepared via lithiation into methyl groups with BuLi/THF with subsequent carboxylation and acidification. The average content of COOH groups per repeat unit was 0.22.
Estimated Errors:
Ambient temperature: No information given.
