Abstract
Abstract The polymers resulting from reaction of a alpha , alpha , alpha ', alpha '-tetrahaloxylene with a diamine of the type H2NANH2, where A is a divalent aromatic moiety, may be doped with a variety of materials to afford electrically conducting polymeric compositions. Both p-type and n-type conductors may be formed either by chemical or electrochemical doping procedures.

Claim 1
Independent Claim
67 words
An electrically conducting polymer composition comprising a polymer whose repeating unit has the structure, (═CH--Y--CH═N--Z--N═) where Z is an aromatic divalent moiety whose parent is selected from the group consisting of benzene, napthalene, anthracene, biphenyl, diphenylmethane, azobenzene, anthraquinone, pyridine, acridine and stilbene and Y is an aromatic divalent moiety whose parent is benzene, and a p-type or n-type dopant in an amount sufficient to increase electrical conductivity.
Claim 2
Dependent Claim
