Methodology:
A standard pressure decay system [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.
Sample Information:
- 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.
Measurement Errors:
Ambient temperature: No information given.
