A series of copolymers were prepared by chemically oxidative polymerization of pyrrole (PY) and ortho ‐toluidine (OT) in HCl aqueous medium. The yield, intrinsic viscosity, and solubility of the copolymers were studied by changing the monomer molar ratio. The resulting PY/OT copolymers were identified by FTIR, 1 H–NMR, DSC, and WAXD techniques. The experimental results showed that the oxidative polymerization of pyrrole and o ‐toluidine is exothermic and the resulting polymers exhibit an enhanced solubility in most organic solvents compared with that of pyrrole homopolymer. The polymer obtained is a real and amorphous copolymer containing pyrrole and o ‐toluidine units. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 82: 510–518, 2001
