PROBLEM TO BE SOLVED To react with a catalyst when used for an electrode because it is specified that a sulfonic acid group is introduced into a side chain, and the chain number is regulated and is randomly introduced into a polymer. Provided are an efficient polyarylene and a method for producing the same, and a solid polymer electrolyte containing the polyarylene, a proton conductive membrane, and a battery electrode. The polyarylene having a sulfonic acid group of the present invention includes a structural unit represented by the following general formula (1), a structural unit represented by the following general formula (2), and the following general formula (3). It consists of at least 1 type chosen from the structural unit represented, The average of the chain number of the structural units represented by General formula (1) is 1.0-4.0, It is characterized by the above-mentioned. [Chemical 1] (In the formula, m represents an integer of 0 to 10, X represents a divalent organic group or a direct bond, and Ar represents an aromatic group.) [Selection figure] None |
