ABSTRACT:
Novel blended membranes are disclosed useful for the pervaporation separation of water-acetic acid mixtures and other miscible multicomponent systems. The blended membranes are formed from polyacrylic acid and nylon 6 or from polyvinyl alcohol, polyacrylic acid and nylon 4 or 6 by blending solutions of the materials, casting the blend and cross-linking the cast membrane.
