Abstract: Electrorheological and dielectric properties of suspensions of polyphenylenediamine isomers in silicone oil have been investigated. The effectiveness of the base forms of polymers was higher than that of their protonated counterparts. The dielectric spectra showed a low rate of polarization which support the idea of mechanism of interfacial particle polarization. The diferences in the low-shear-rate relative apparent viscosity of the systems were explained as a result of different particle dipole coefficients.
