POLYVINYL COPOLYMER, DOPANT HAVING SAME, CONDUCTIVE POLYMER COMPOSITE HAVING THE DOPANT

摘要

The present invention relates to a polyvinyl copolymer having one or more lateral branch sulfonic acids attached on the hydroxy group of a polyvinyl alcohol or a polyvinyl phenol and a preparation method therefor, a dopant having same, and a conductive polymer composite having the dopant and a conductive polymer, and a preparation method therefor, wherein the electrical conductivity, dispersibility, solubility, heat resistance and environmental resistance of the conductive polymer composite is enhanced by using the dopant having the copolymer.
