Notes:
The heterogeneous acetal-based membranes containing 50, 60, 70, 80, and 90% (w/w) of the sulfonated polystyrene crosslinked with 7% divinyl benzene were fabricated and studied. In addition, the heterogeneous acetal-based membranes of 85% (w/w) sulfonated polystyrene crosslinked with 1, 4, and 7% divinyl benzene were also prepared and studied. The gel water content, dimensional stability, ion-exchange capacity, area and specific ohmic resistance, permselectivity, and rate of ion exchange of the acetal-based membranes were determined. The sulfonated polystyrene crosslinked with 7% divinyl benzene resin was found to be the better material for preparing the acetal-based membrane with comparable good characteristics. A commercially available heterogeneous membrane (Shanghai Chemicals, 3361) of dry-molding sulfonated polystyrene-divinyl benzene resin was used as the reference membrane for the present investigation. © 1995 John Wiley & Sons, Inc.
