The infrared spectra and dielectric properties of cotton celluloses I and II, γ‐irradiated in the presence of organic solvents have been investigated. The obtained data showed that irradiation of cotton celluloses I and II in organic solvents helps in oxidation of these celluloses and increases their dielectric constant. Examination of the infrared spectra and X‐ray diffraction (XRD) patterns revealed that irradiation of cotton celluloses I and II in organic solvents produces considerable changes in their crystallinity. It was found that the highest values of crystallinity and dielectric constant are obtained when the samples are irradiated in chloroform whereas the lowest values are obtained when the samples are irradiated in toluene.
