Formation and thermal transformations of radicals in γ-irradiated cellulose

The work is aimed at more detailed theoretical analysis of the structure of radicals in cellulose gamma-irradiated at 77 K, specification of the mechanism of their formation, as well as studying reactions of transformation of radicals in the case of temperature increase. It is established that in the case of cellulose gamma-irradiation radicals appear with the localization of an unpaired electron in 1 and 4 positions of the pyranose cycle the formation of which is accompanied by the disruption of the glycoside bound. Thermal transformations of these radicals are conditioned by their dehydration and occur with the formation of radicals of the allelow type
