説明
<jats:title>Abstract</jats:title> <jats:p> Carbon dioxide and methane gas permeabilities, solubilities and diffusivities for poly [N, N′‐(phenoxyphenyl)‐pyromellitimide] films synthesized in our laboratory are contrasted with values measured for a chemically identical commercial polyimide film, Kapton H. The synthesized samples exhibited greater permeabilities, solubilities, and diffusivitles than those of the commercial sample. At the same time, the higher carbon dioxide permeability is associated with only a moderate reduction in permselectivity for the CO <jats:sub>2</jats:sub> /CH <jats:sub>4</jats:sub> system. The increased sorption and transport coefficients for the synthesized sample are attributed to a lower degree of aggregation and orientation of this film as compared to the Kapton H sample. </jats:p>
