ABSTRACT:
Organic compositions of conductive polymers are provided. The compositions have at least one polymer selected from polypyrrole, polythiophene, or combinations and at least one colloid-forming polymeric acid dispersed in a liquid medium that is at least 60% by weight at least one organic liquid. Also provided is a method of making such compositions.
