Abstract
Abstract A polymer solution is formed from a sulfur- or oxygen-containing aromatic polymer solute such as poly(phenylene sulfide) or poly(phenylene oxide), a Lewis Acid solute derivative (dopant) such as arsenic hexafluoride and a liquid halide solvent such as arsenic trifluoride. The solutions are especially useful for casting conductive polymer articles.
