Abstract
Abstract The polymers resulting from reaction of a 1,1,2,2-tetrahaloethane with a diamine of the type H 2 NANH 2 , where A is a divalent aromatic moiety, may be doped with a variety of materials to afford electrically conducting polymeric compositions. Poly(ethyleneiminobenzene) is an especially useful material. Both p-type and n-type conductors may be formed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
55 words
An electrically conducting polymer composition comprising a polymer whose repeating unit has the structure, (═CH--CH═N--A--N═) where A is an aromatic divalent moiety whose parent is selected from the group consisting of benzene, napthalene, anthracene, biphenyl, azobenzene, pyridine, acridine and stilbene and an effective amount, sufficient to increase electrical conductivity, of a n-type or p-type dopant.
Claim 2
Dependent Claim
55 words
An electrically conducting polymer composition comprising a polymer whose repeating unit has the structure, (═CH--CH═N--A--N═) where A is an aromatic divalent moiety whose parent is selected from the group consisting of benzene, napthalene, anthracene, biphenyl, azobenzene, pyridine, acridine and stilbene and an effective amount, sufficient to increase electrical conductivity, of a n-type or p-type dopant.
Claim 3
Dependent Claim
12 words
The composition of claim 1 where A is the 1,4-divalent benzene moiety.
Claim 4
Dependent Claim
12 words
The composition of claim 1 where the dopant is an n-type dopant.
Claim 5
Dependent Claim
18 words
The composition of claim 3 where the dopant is an alkali metal salt of an aromatic radical anion.
Claim 6
Dependent Claim
12 words
The composition of claim 1 where the dopant is a p-type dopant.
Claim 7
Dependent Claim
18 words
The composition of claim 5 where the dopant is a quaternary ammonium salt of an unreactive non-nucleophilic anion.
Claim 8
Dependent Claim
41 words
The composition of claim 5 where the dopant is selected from the group consisting of chlorine, bromine, iodine, SbF 5 , AsF 5 , PF 5 , AgX, NO 2 X , and NOX where X is an unreactive, non-nucleophilic anion.
Claim 9
Dependent Claim
20 words
The composition of claim 1 where an effective amount is a mole ratio of dopant to polymer to about 5.
