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 which may be prepared in good yield from the reactants in a dipolar aprotic solvent in the presence of a base.
