Method/Apparatus/Procedure:
Pressure decay method was used for sorption measurements. The cell employed was similar to the one described in ref. (1).
Source and Purity of Materials:
Polyimide was obtained by condensation of pyromellitic acid dianhidride and oxydiphenylenediamine with subsequent thermal imidization at 473 and 673 K. These samples and commercial polyimide Kapton H (Toray - DuPont Inc.) had the following densities: 1.405, 1.429, and 1.431 g/cm
3
, respectively. No information given on carbon dioxide purity.
