각 A 블록이 설폰산 또는 설폰산염 에스테르 작용기를 본질적으로 함유하지 않고 각 B 블록이 이 B 블록의 설폰화 민감성 단량체 단위의 수를 기준으로 약 10 내지 약 100mol% 설폰산 또는 설폰산염 에스테르 작용기를 함유하는 중합체 블록인, 적어도 하나의 말단 블록 A와 적어도 하나의 내부 블록 B를 보유하는 적어도 하나의 설폰화된 블록 공중합체를 비양성자성 극성 용매에 용해시켜 제조한 설폰화된 블록 공중합체 조성물. 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.
