Abstract

1,216,159. Ion exchange membranes. RHONE-POULENC S.A. 29 Aug., 1969 [2 Sept., 1968], No. 43100/69. Heading B5B. [Also in Division C3] Ion exchange membranes comprise particles of an ion exchange resin in a matrix of vinyl chloride-alkyl maleate copolymer. In the examples, a vinyl chloride-butyl maleate copolymer is dissolved in tetrahydrofuran, mixed with particles of an ion exchange resin impregnated with acetone and cast into a film, then immersed in a water bath for 15 minutes. Optionally the film is dried and subjected to pressure. Ion exchange resins used are crosslinked polystyrene carrying quaternary ammonium groups or sulphonic acid groups.
