Despite efforts by the membrane community to develop polymeric materials with improved O 2 /N 2 separation performance, limited progress has occurred for almost a decade. Molecular sieving media, which can exhibit gas separation properties superior to polymers, tend to be brittle and uneconomical to

The temperature dependence of the gas permeability and sorption coefficients of a series of ladder-type polypyrrolones, 6FDA-TAB and 6FDA/PMDA-TAB copolymers, is reported at temperatures up to 80ยฐC. Knowledge of gas transport and sorption behavior at higher temperatures provides insights into these
