Abstract: MEMBRANES SPECIALLY ADAPTED TO PREFERENTIALLY PERMIT THE PASSAGE OF RELATIVELY PURE WATER THROUGH THEM, WHILE RESISTING THE PASSAGE OF DISSOLVED SALTS MUST CONVENTIONALLY BE KEPT WATER-WET IN ORDER TO RETIAN THIS ABILITY TO EXCLUDE SALTS. DRY, REWETTABLE, STABILIZED MEMBRANES IN WHICH THIS DESIRABLE PROPERTY IS PRESERVED, CAN BE MADE BY TREATING THE WET MEMBRANE FIRST WITH A WATER-MISCIBLE SOLVENT, THEN WITH A NON-POLAR ORGANIC SOLVENT AND FINALLY DRYING THE MEMBRANE. THE PRESENCE OF A WATER-SOLUBLE POLYOL IN THE DRY MEMBRANE RESULTS IN STILL BETTER PROPERTIES.
