Abstract

Poly(o-toluidine) (POT) and poly(m-toluidine) (PMT) blends with polystyrene of five different compositions were prepared by solution blending using THF as the solvent in which both the $POT-HNO_3$ and $PMT-HNO_3$ bases are almost completely soluble. The blends have been characterized by spectral, thermal and electrical measurements. The results suggest that blend formation occurs at all compositions presently studied. The thermal stability of the respective blends is higher than that of the $POT-HNO_3$ and $PMT-HNO_3$ salts. The maximum conductivity of the blends is $9.2 X 10^{-4} S cm^{-1}$. The results show that POT/PMT can be blended with up to 30% wt/wt of polystyrene without a significant drop in its conductivity.
