NOVEL POLYTHIOPHENE DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide a process for the preparation of dispersions or solutions comprising polythiophene+An-ion complexes in anhydrous or low-water-content organic solvents. SOLUTION: The process for the preparation of dispersions or solutions comprising polythiophene+An-ion complexes comprises the steps of: adding at least one water-miscible organic solvent or a water-miscible solvent mixture to an aqueous dispersion or solution comprising optionally substituted polythiophenes; removing all or some of the water; and diluting, if desired, the resulting dispersion or solution with organic solvents. According to this preparation process, the dispersion or solution comprising 0.2-5 mass% polythiophene+An-ion complex in the organic solvent of 0-20 mass% water content can be prepared.
