Abstract
The destruction of cellulose by the action of fast electrons was studied. T he irradiation conditions for realization of the high-temperature mode of d estructive decomposition of the polymer without using additional heat sourc es were determined. Cellulose was heated up to 430 K at the, dose rate of 9 .0 kGy/s or higher and the total absorbed dose of 300 kGy. Under these cond itions, the radiation-chemical yield of scission considerably increases and is much higher than the corresponding yield at room temperature.
