Abstract:
Sulfonated block copolymer composition formed by dissolving in an aprotic polar solvent at least one sulfonated block copolymer having at least one end block A and at least one interior block B wherein each A block contains essentially no sulfonic acid or sulfonate ester functional groups and each B block is a polymer block containing from about 10 to about 100 mol% sulfonic acid or sulfonate ester functional groups based on the number of sulfonation susceptible monomer units of the B block.
