Using the results of kinetic studies of free radical recombination in cellulose and in some model compounds, some data as to their structure were obtained. Cellulose is characterized by the distribution function of microregions with different energy of molecular interaction. The minimal value of activation energy of macromolecule movement is 37-42 kJ/mol (1.5-2 hydrogen bonds per glucopyranose ring), the maximal one is 63-105 kJ/mol corresponding to the most ordered (crystalline) regions of cellulose. After amorphization of cellulose the warming-up by stages curve points to even distribution by the forces of molecular interaction.
