摘要：

The gas permeability and permselectivity of unmodified and aryl nitrated poly (phenylene oxide) and polysulfone are reported for CO2, CH4, O2 and N2. Aryl nitration decreases the permeability for all the gases, but increases the permselectivity of both polymers for either O2/N2 or CO2/CH4 gas pair. These results are related to changes in packing density, torsional mobility and interchain attractions due to the polar nitro group.
