Modified polysulfone membranes. IV. Gas separation with aminated polysulfone membranes

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/N2 separation and a significant increase in that toward O2 in O2/N2 separation.Peer reviewed: YesNRC publication: Ye
