Newly synthesized poly(azomethine urethanes) in thin films were deposited onto glass substrates from dimethylformamide solutions. Temperature dependences of the electrical conductivity and thermoelectric power were studied. The investigated polymers have interesting semiconductor characteristics. The values of important parameters of these films (activation energy of electrical conduction, charge carrier concentrations, and ratio of carrier mobilities) were calculated. The nature of the electrical conduction mechanism in the respective polymers is discussed. Transmission and absorption spectra were studied in the spectral domain, 300-1250 nm.
