(57) [Problem] To obtain a high molecular weight poly (thioarylene) compound using a precursor that can react under mild conditions. SOLUTION: The following formula [1] (Each of R 1 to R 8 represents a hydrogen atom, a halogen atom, It represents a lower alkyl group or an alkoxy group, and may be the same or different. X represents an oxygen atom or a sulfur atom. n indicates the degree of polymerization as an integer of 2 or more. Is produced by a dealkylation or dearylation reaction of a poly (arylene sulfonium salt) compound as a corresponding precursor. |
