Transport of Gases and Organic Vapours Through Membranes Made of Poly(amide-imide)s Crosslinked with Poly(ethylene adipate)

Abstract

Transport of permanent gases (N2, O2, CO2) and of saturated organic vapours of benzene, toluene and methanol through membranes based on poly(ethylene adipate)-crosslinked poly(amide-imide)s was studied. The membranes containing more than 50 wt.% of non-polyimides showed higher permeability coefficients (by 2-3 orders) for the organic vapours than for the gases.
