Polymer solutions are formed by reacting an aromatic heterocyclic such as thiophene, substituted thiophenes or oligomers of either with an acceptor doping agent (Lewis Acid) such as arsenic pentafluoride in the presence of certain solvents such as arsenic trifluoride. Articles such as air-stable conductive poly(3-methylthiophene) are cast from such solutions.

Simultaneous polymerization, doping and solubilization of heterocyclic

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.

Solution of a chalcogen-containing polymer and process of forming

Rechargable battery with a conjugated backbone polymer anode which has been coated, when in the reduced state, by contact with a monomer with a reactive oxirane group. Reduced polyacetylene anodes, after reaction with ethylene oxide, offer improved stability to solvents.

Battery having polymeric anode coated with reaction product of oxirane

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 strong acid solvent such as sulfuric acid. Solvents such as fluorosulfonic acid may also serve to generate the dopant. The solutions are especially useful for casting polymer articles.
