Embodiment 1

[0076] 4 ml of distilled water was supplied into the reaction vessel, and 0.44 g (2.1 mmol, corresponding to 0.35 mol / L) of sodium 2-naphthalenesulfonate (hereinafter abbreviated as 2NaNS) was added as a surfactant. Subsequently, 0.28 g (2.0 mmol, corresponding to 0.33 mol / L) of 2,3-dihydrothiophene[3,4-b][1,4]dioxin (hereinafter abbreviated as HTDO) was added as a polymerizable monomer, stir the mixture. To this solution, a solution obtained by adding 0.28 g (0.7 mmol, corresponding to 0.12 mol / L) of iron(III) sulfate as an oxidizing agent to 2 ml of water was added dropwise over 1 hour to start the reaction. The reaction was carried out with stirring at a temperature of 20° C. for 15 hours. The resulting black polymer was filtered and the filtrate was washed with distilled water until the pH was 7. Then, the solution was washed twice with acetone, and vacuum-dried at 40° C. for 10 hours. The mass of the obtained polymer was 0.17 g. Subsequently, use a pressure of 3t / cm ...

Embodiment 2

[0078] The reaction was carried out under the same conditions as in Example 1, except that the amount of the surfactant was 0.55 g (2.6 mmol, equivalent to 0.44 mol / L). The mass of the obtained polymer was 0.17 g, and the results of measuring the electrical conductivity are shown in Table 1.

Embodiment 3

[0080] The reaction was carried out under the same conditions as in Example 1, except that the amount of the oxidizing agent was 0.20 g (0.5 mmol, equivalent to 0.086 mol / L). The mass of the obtained polymer was 0.16 g, and the results of measuring the electrical conductivity are shown in Table 1.

Abstract

The present invention provides a process for producing a conductive polymer, characterized by comprising conducting polymerization in the presence of a polymerizable monomer, a surfactant, a solvent and an oxidizing agent under initial conditions that a concentration of the polymerizable monomer is from 0.20 to 2.8 mol / L and a molar ratio of the surfactant is from 0.8 to 1.6 mol per mol of the polymerizable monomer; and a conductive polymer obtained by the method. Since the conductive polymer of the present invention has high conductivity, it is useful as constituent members of electrochemical elements.
