Abstract: This invention is directed to the fabrication of embossed ionexchange membranes. The procedural steps include the making of such membranes by the insertion of such component parts as bottom and top sheets of plate glass having therebetween liquid ion exchange monomers, porous sheets of membrane reinforcing materials and patterned flexible metal plate molds. After heat polymerization of the monomers, the mold is peeled off to produce the embossed ion exchange membrane. There is also disclosed a modified procedure for producing ion-exchange membranes with both surfaces embossed.
