<P>PROBLEM TO BE SOLVED: To provide a sulfonated polymer that can retain excellent resistance to hot water even when the introduction of sulfonic acid groups is increased, to provide a solid polyelectrolyte that is composed of the sulfonated polymer and has high proton conductivity and shows excellent electrogenicity and provide a proton conductive film. <P>SOLUTION: This polyarylene polymer has a constitution unit that is led from a compound having a specific structure, preferably includes a constitution unit represented by general formula (1") [wherein n is an integer of 1 or more, Q includes 99 to 20 % mol of structure represented by general formula (2') and 1 to 80 % mol of the structure represented by general formula (3'-1) and/or general formula (3'-2)]. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
