Abstract

A conducting organic polymer is disclosed consisting of a polypyrrole or an N-substituted analog of pyrrole and a non-nucleophilic polymeric anion. The polymer is formed by electropolymerizing pyrrole from an electrolyte containing a non-nucleophilic polymeric anion and pyrrole.

Claims

1. A conducting organic polymer having the following formula:

##STR4## wherein A is a non-nucleophilic polymeric anion having a charge of -y.

2. The conducting organic polymer as claimed in claim 1 wherein A is a polystyrene sulfonate.

3. The conducting organic polymer as claimed in claim 1 wherein A is a polyvinyl sulfonate.

4. The conducting organic polymer as claimed in claim 1 where A is polyacrylamidomethylpropanesulfonate.

9. The conducting organic polymer of claim 1 wherein the polymer is polypyrrolepolystyrenesulfonate having the following composition:

92% C₄ H₃ N(C₈ H₇ SO₃)₀.25 ; and

10. The conducting organic polymer of claim 1 wherein the polymer is polypyrrolepolyacrylamidomethyl propane sulfonate having the following composition:

91% C₄ H₃ N(C₇ H₁₂ NSO₄)₀.20 ; and

9% oxygen.

5. A conducting organic polymer comprising:

a polypyrrole; and

a non-nucleophilic polymeric anion.

6. The conducting organic polymer as claimed in claim 5 wherein said polypyrrole comprises an N-substituted analog of pyrrole.

7. The conducting organic polymer as claimed in claim 6 wherein said N-substituted analog of pyrrole comprises poly-N-phenylpyrrole.

8. The conducting organic polymer as claimed in claim 6 wherein N-substituted analog of pyrrole comprises a poly-N-methylpyrrole.
