(DE19507104-A1)      Anion exchange mouldings are made from a soln. of: (a) polymer with reactive functional gps. contg. halogen: and (b) tert. amine (I) by evapn. of the solvent or phase inversion. The polymer is a polyether (II), which is soluble in the solvent mixt. and has a main chain of ethylene oxide gps. contg. structures of formula -(CR1R2-CR3R4-O-)n- (IIA). At least one of R1-4 = CH2Z, where Z = halogen. (I) contains 2 or more tert. amino gps..    USE -   The mouldings are used as diaphragms for fuel cells, microporous substrates for gel electrophoresis and selective layers for gas sepn. or pervaporation membranes, for making charged reverse osmosis, ultrafiltration and microfiltration membranes and for ion-conducting bonding of ion exchange membranes (all claimed).    ADVANTAGE -   The universally-applicable strongly basic anion exchanger can be made in any physical form (e.g. blocks, granules, coatings on substrates and for bonding). Although strongly basic, it is made without using toxic (carcinogenic) chloromethylating agent. It is chemically stable (esp. towards high and low pH values and oxidn.), has satisfactory mechanical stability and can be made cheaply and easily.
