摘要：

Novel gas permeation membranes were prepared from polysulfones and amine-modified polysulfones. The introduction of the primary amine moiety into polysulfone membranes led to an increase in permselectivity toward CO2 in CO2/N-2 separation and a significant increase in that toward O-2 in O-2/N-2 separation.
