COPOLYMER, METHOD FOR PRODUCING THE SAME, CONDUCTIVE POLYMER AQUEOUS SOLUTION THEREOF, AND USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide: a novel water-soluble copolymer having a high conductivity; an aqueous solution thereof; and a use thereof.SOLUTION: Provided is a copolymer comprising a repeating unit represented by formula (M1) (referred to as "thiophene monomer") and at least one repeating unit selected from (M2), (M3), and (M4) (referred to as "comonomer"), and in which thiophene monomer and comonomer may be self-doped and in which the ratio of thiophene monomer/comonomer (mole/mole) is 3 to 9999.SELECTED DRAWING: None
