N2 - Membranes for hydrogen separation represent an attractive alternative to current methods to further lower the costs of hydrogen production. A highly contorted ladder polymer was prepared and evaluated for gas transport. The membrane permeabilities were consistent with those of a polymer containing large amount of free volume. Single gas permeabilities were measured for He, H2, CO2, O2, N2, and CH4 at 35°C using the time lag method. Spiro polymer 1 showed high permeability for each gas with H2 having the highest permeability of 1763 Barrers. While permeabilities were high, permselectivities were also good, particularly for O2/N2, H2/CH4, and CO2/CH4 separations.
