Poly(o-toluidine) (POT) and poly(m-toluidine) (PMT) blends containing 10, 30, 50, 70 and 90 wt% of polymethylmethacrylate (PMMA) were prepared by solution blending using formic acid (HCOOH), which serves both as a dopant and as a solvent in which PMMA, POT-HCOOH base and PMT–HCOOH base are soluble. The blends have been characterized by spectral, thermal and electrical measurements. The infrared spectra suggest that blend formation occurs at all the compositions presently studied. The thermal stability of the blends is higher than that of POT–HCOOH and PMT-HCOOH salts. The conductivity of POT (70)-PMMA (30) and POT (90)-PMMA (10) blends is close to that of POT-HCOOH salt, indicating that POT can be blended with up to 30 wt% of PMMA without significance drop in its conductivity.
