Abstract: The resistivity of some synthesized nitroaryl and aminoaryl derivatives of cellulose prepared by condensation of aromatic aldehydes with hydroxyethylcellulose was investigated. The temperature dependence of resistivity of the prepared derivatives obeys the relationship valid for semiconductors. The values of resistivity depend on character of the present chromophore and the high values of resistance are reached in case the polymer contains only a nitroaryl group. The simultaneous presence of acceptor and donor group reduces the resistivity by six decimal orders. The values of the resistivity activation energies of the prepared derivatives vary in the range 0.42—0.63 eV.
