Poly(1-N-vinylimidazole) (PVIm) was obtained by the radical polymerization of 1-N-vinylimidazole in a benzene solution under an inert atmosphere at a temperature of 600C. Its hydrophilic derivative was synthesized by chemical modification of PVIm with 3-bromopropilamine hydrobromide. The structure of the synthesized polymers was studied by IR spectroscopy. The electrophysical and optical properties of PVIm and its derivatives were studied. The temperature dependence of electrical conductivity, voltammetric behavior, photoconductivity kinetics, and optical band gap values of these polymer materials were determined. This work was carried out in the 300–360 K temperature range and in the 0–100 V voltage range. It was confirmed that electrical conductivity in all samples obeyed Ohm's law.
