ABSTRACT:
The present invention provides a sulfonic group-containing polyarylene block copolymer superior to the perfluoroalkylsulfonic acid polymers in cost, conductive properties and proccessability, a process for producing the copolymer, a solid polymer electrolyte and a proton conductive membrane.The sulfonic group-containing polyarylene block copolymer includes a polymer segment with an ion conductive component represented by the formula (A) and at least one polymer segment without an ion conductive component represented by the formulae (B-1), (B-3) and the like and containing an aromatic ring bonded at the meta-positions or ortho-positions:wherein X is a single bond, —CO—, —SO2— or the like; W is a single bond, —CO—, —SO2— or the like; Q is a single bond, —O—, —S— or the like; J is a single bond, —CO—, —SO2— or the like; and R1to R24are each a hydrogen atom, a fluorine atom, an alkyl group or the like.
