Abstract�� The polyacrylic acid has been prepared by solution polymerization.The polyacrylic acid/polysulfone amide(PAA/PSA)composite membrane is made with the crosslinking reaction of the polyacrylic acid and the cross linker,epoxy.The membrane can be used for concentrating ethanol from dilute ethanol water mixture through pervaporation process owing to its alcohol permselective properties.
