PREPARATION METHOD OF CONDUCTIVE POLYMER FOR ELECTROLYTIC CAPACITOR

摘要

The present invention relates to a method for preparing a polymer for using as a dopant of a macromolecule for a solid condenser, and to a method for preparing a water dispersive conductive macromolecule for the solid condenser using the same. More particularly, according to the present invention, provided is a method for preparing a water dispersive conductive macromolecule having excellent electrical properties and showing a higher breakdown voltage with respect to conventional macromolecules using a sulfonic acid-based polymer such as polyvinylsulfonic-co-styrenesulfonic acid as a dopant, wherein the sulfonic acid-based polymer is obtained by the polymerization of sodium styrenesulfonate and a specific sulfonic acid-based monomer.
