Abstract The synthesis of poly( m ‐aminophenyl propionic acid) (PAPPA) was carried out by polymerization in different aqueous media, from the respective monomer, using ammonium persulfate as oxidizing agent. The copolymer of aniline and m ‐aminophenyl propionic acid was also synthesized. The polymers were characterized by FTIR, UV‐vis, X‐ray electron spectroscopy, nuclear magnetic resonance spectroscopy, elemental analysis, thermal stability analysis (TGA), and electrical conductivity. PAPPA showed a high doping by HCl and H 2 SO 4 . If the composition of the comonomer acid decreases, the incorporation of copper ion and the electrical conductivity are increased. Thermal stability is favored by an increase of the content of aniline and copper ions. The polymeric structures have amine and imine groups. The last units are preferentially doped. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 90: 706–715, 2003
