In this study, poly(o-anisidine) [POA], poly(o-anisidine-co-aniline) [POA-co-A], and polyaniline [PANi] were chemically synthesized using a single polymerization process with aniline and o-anisidine as the respective monomers. During the polymerization process, p-toluene sulfonic acid monohydrate was used as a dopant while ammonium persulfate was used as an oxidant. N-methyl-pyrolidone (NMP) was used as a solvent. We observed that the ATR spectra of POA-co-A showed features similar to those of PANi and POA as well as additional ones. POA-co-A also achieved broader and more extended UV-vis absorption than POA but less than PANi. The chemical and electronic structure of the product of polymerization was studied using Attenuated Total Reflectance spectroscopy (ATR) and UV-visible spectroscopy (UV-vis). The transition temperature of the homopolymers and copolymers was studied using differential scanning calorimetry and the viscosity average molecular weight was studied by using dilute solution viscometry.
