Abstract:
A method of forming an oligomer from monomers of Formula I: wherein R1 and R2 are independently selected from the group consisting of â€”H, â€”OH, â€”COOH, halogen, â€”NO2, â€”NH2, and substituted and unsubstituted alkyl, substituted and unsubstituted alkoxy and substituted and unsubstitued aryl groups; R1 substitutions being ortho or meta to the NHR2 group; and m is 0 to 4, the method comprising,reacting the monomer of Formula I, or a derivative or water-soluble salt thereof, with greater than 10 mole percent of an initiator, in the presence of a chemical oxidant and/or an applied electrochemical potential, said initiator comprising a substituted or unsubstituted aromatic amine which has a lower oxidation potential than the monomer of Formula I and which is capable of being incorporated in a chain resulting from the reaction, wherein the oligomer has a molecular weight of less than 2300, and wherein the method provides an oligomer having a substantially monomodal molecular weight distribution.
