AbstractThin film of poly (5-isopropylidenecyclo-1,4-vinylene-2,3-dicarboxylicacidamide-s-methyl hydrazinecarbodithioate) (II) (Scheme 1) of 5 μm thickness was prepared. The dielectric properties of the prepared sample were studied as a function of frequency and temperature, and the results were analyzed by the Cole–Cole method. The optical permittivity and the dc-conductivity have been deduced, and the activation energy has been calculated and found to be 0.023 eV. Also, a detailed study of optical absorption is presented. The optical absorption spectra were measured in the wavelength range from 200–600 nm. The calculated absorption coefficient, absorption index, and determined values of energy gaps (equation image and ΔE) are presented. The results indicate that both mechanisms of direct and indirect transitions exist. © 1997 John Wiley & Sons, Inc. J Appl Polym Sci 65:1653–1657, 1997
