A series of copolymers were synthesized by chemically oxidative polymerization of pyrrole (PY) and m-Toluidine (cas 108-44-1) (MT) in hydrochloride aqueous medium at ambient temperature. The yield, intrinsic viscosity, and solubility of the copolymers were studied by changing PY/MT molar ratio from 0/100 to 88/12. The as-prepared PY/MT copolymer bases were characterized by FT–IR, UV–VIS, 1H NMR, DSC, and wide-angle X-ray diffraction. The results suggested that the oxidative polymerization from pyrrole and m-toluidine is exothermic and the resulting copolymers are more easily soluble in most of the organic solvents than polypyrrole. The polymer obtained is a real copolymer containing pyrrole and m-toluidine units, but the PY content calculated on the basis of the proton NMR spectra is lower than feed PY content.
