POLYMERIZATION SOLUTION CONDUCTIVE POLYMER FILM OBTAINED FROM POLYMERIZATION SOLUTION AND SOLID ELETROLYTIC CAPACITOR

摘要

A polymerization liquid for electrolytic polymerization comprising borodisilic acid and / or a salt thereof as a supporting electrolyte is provided which is capable of suppressing precipitation by hydrolysis of borodisilylic acid ions and supplying a conductive polymer having high heat resistance do. The polymerization solution of the present invention is prepared by mixing a solvent comprising 100 to 80 mass% of water and 0 to 20 mass% of an organic solvent, at least one monomer having a? -Conjugated double bond, and a mixture of borodysalicylic acid and borodisalicylic acid salt And at least one stabilizer selected from the group consisting of nitrobenzene and a nitrobenzene derivative, wherein the content of the stabilizer is at least one selected from the group consisting of Is more than 1/8 mol relative to 1 mol of the supporting electrolyte. A complex of the stabilizer and borodysalicylic acid is formed to inhibit precipitation by hydrolysis of borodisilicylic acid ions.
