Polyaniline and its derivative, poly(o-toluidine) have various molecular weights depending on the synthetic condition. The factors affecting on molecular weight are the kind of acid, the time of adding oxidant, synthetic temperature, etc.
The acids of HCl, H2SO4, and H3PO4 were used. The synthetic temperature were room temperature, 0℃, and -10℃. The molecular weight of polyaniline was identified by GPC. The change of electrical conductivity depending on the change of molecular weight of polyaniline was studied.
