The bulks as well as surface resistivity of these polymers indicate that the polymers behave like a semiconducting material evident from the values of bulk resistivity (10⁹ to 10⁸ ohm cm) and surface resistivity (10¹ to 10³ ohm) of the polymers at room temperature. The effects of electric field and temperature on resistivity of the polymers have also been investigated. Variation of dielectric constant and loss of the polymers with frequency (100 Hz to 10kHz) and temperature (room temperature to 80°C) has been studied. The change of electrical (bulk) conductivity of the blends with the blend composition has also been investigated. The band gap of the samples was found to be varying from 1.9 to 1.12 eV.</span>
