Abstract:
A process for forming a water-soluble, electrically conductive composition of matter capable of forming a stable 5 wt. % solution in water, comprising a polyacid and a conjugated polymer composed of repeating units which contain a conjugated basic atom, the process comprising forming an aqueous solution of one or more monomers which contain a conjugated basic atom, and a polyacid, wherein the number of acid groups on said polyacid exceeds the number of said basic atoms, and polymerizing the monomer while controlling the rate of initiation and the rate of propagation of said polymerization such that the polymerization forms said composition of matter in said solution, said one or more monomers are selected from the group consisting of substituted and unsubstituted aniline, thiophene, pyrrole, p-phenytene sulfide and mercaptophenol, said polyacid is selected from the group consisting of poly (acrylic acid), poly (methacrlic acid), poly (styrenesulfonic acid), poly (vinylsulfonic acid), poly (styrene boric acid), poly (vinyl boric acid), poly (vinyl sulfuric acid), poly (styrenephosphoric acid), poly (vinyl phosphoric acid), poly (styrene phosphonic acid), poly (vinyl phosphonic acid), precipitating said composition of matter from said solution to form a precipitate and washing said precipitate.
