Abstract of corresponding document: US4511711
A process for producing a semipermeable membrane having a high flux,
excellent in solute rejection and useful for reverse osmosis,
ultrafiltration and the like which comprises dipping a semipermeable
membrane of acrylonitrile polymer containing 40-100% by mole of
acrylonitrile in a solution of an amine and/or an alkali, or casting a
solution of said polymer containing an amine and/or an alkali to
prepare a semipermeable membrane, and optionally, treating the
