Increasing interest by governmental entities to realize a future in which hydrogen is a dominating fuel source has spurred great interest in all aspects of hydrogen production, storage, and utilization. McKeown et al. at the University of Manchester presented a series of highly porous polymers, which have good thermal and mechanical stability. One of these microporous polymers was prepared and its permeability for use in hydrogen and other light gas separations was evaluated. Poly(3,3,3′,3′-tetramethyl-1,1′-spirobisind ane-5,5′,6,6′-tetrol-co-2,3,5,6-tetraflourophthal onitrile) represents an "upper bound" membrane material for O 2/N 2, H 2/CH 4, and CO 2/CH 4 separations with respect to permselectivity vs. permeability. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA, 8/22-26/2004).
