NOVELTY - Producing shaped article, involves: providing a composition comprising an amine neutralized sulfonated block copolymer comprising two polymer end blocks A and at least one polymer interior block B, where each A block contains essentially no sulfonic acid or sulfonate functional groups and each B block comprises sulfonation susceptible monomer units and sulfonic acid or sulfonate ester functional groups partially or completely neutralized by an amine; heating the composition to a temperature at which the sulfonated block copolymer is moldable; followed by shaping and cooling.    USE - For producing a shaped article in the form of a sheet, fiber, hollow body, membrane or film, used in an apparatus selected from fuel cells, filtration devices, devices for controlling humidity, devices for forward electrodialysis, devices for reverse electrodialysis, devices for pressure retarded osmosis, devices for forward osmosis, devices for reverse osmosis, devices for selectively adding water, devices for selectively removing water, devices for capacitive deionization, devices for molecular filtration, devices for removing salt from water, devices for treating produced water from hydraulic fracturing applications, devices for ion transport applications, devices for softening water, and batteries; in an electro-deionization assembly; and in articles (all claimed) such as diapers and adult incontinence constructions.    ADVANTAGE - The article produced in the form of membrane or film has at least one of the characteristics of: a conductivity of at least 5 mS/cm; an anion exchange selectivity of at least 80%; and a water absorption capacity of at most 20 wt.%, based on the dry weight of the article. The amine neutralized sulfonated block copolymer has a melt flow index of at least 0.5 g/10 minute at 230 degrees C; and 5 kg load according to ASTM 1238. The amine neutralized sulfonated block copolymers have a melt flow index which renders them plastically formable at elevated temperatures. Thus, the amine neutralized block copolymers can be shaped by thermal methods such as molding and melt processing, and can be processed into a broad variety of shapes including shapes which cannot be obtained by casting methods, such as fibers and hollow bodies including tubes. Moreover, the shaped articles which are obtained by molding a composition comprising the amine neutralized sulfonated block copolymer can be treated to convert the amine neutralized groups of the block copolymer into -SO3H groups thus giving access to shaped articles which comprise the sulfonated block copolymer(s) employed in the preparation of the amine neutralized block copolymer(s). The ion and water transporting articles which are obtained by melt processing of compositions comprising the neutralized sulfonated block copolymers can be converted into corresponding articles comprising the non-neutralized, i.e., the sulfonated block copolymers. In such cases, the neutralized sulfonated block copolymers serve as an intermediate product which enables the production of articles comprising the sulfonated block copolymers as the ion or water conducting material by way of thermal processes such as molding and melt processing methods. The present method provides immense benefits over the art as it allows processing a functionalized block copolymer into water or ion conductive articles by a procedure which does not require forming solutions or liquid or gelled dispersions, nor liquid casting steps, nor extraction steps. Modifying the sulfonated block copolymers with amines has surprising impact on the performance of articles comprising these modified block copolymers. The water uptake of articles comprising the modified block copolymers is significantly lower than the water uptake of articles comprising the corresponding sulfonated block copolymers. The reduced tendency of the articles comprising the modified sulfonated block copolymers to take up water results in a distinctly improved dimensional stability of the articles as compared to articles comprising the sulfonated block copolymer under wet conditions. The articles comprising the modified block copolymers exhibit an exceptionally high level of ion conductivity; and the ion transport through a membrane comprising the modified block copolymers is high in spite of the low tendency to take up water. Such membranes exhibit high specific conductivity, high selectivity for cation transport, and low swelling on exposure to water. Accordingly, the modified sulfonated block copolymers are broadly suited for a wide variety of end uses, and are especially useful for applications involving water or which take place in wet environments. In particular, the modified sulfonated block copolymers are broadly suited for electrically driven water separation processes, or for osmotically driven separation processes such as forward osmosis, filtration, and blue energy applications. Additionally, the modified sulfonated block copolymers are melt- processible. As such, the modified sulfonated block copolymers can be processed into ion and water transporting articles of various shapes in a single processing step. Thus, it reduces the cost.
