The influence of an azide plasticizer on the supramolecular structure of nitrocellulose with different nitrogen content was investigated by Wide-angle X-ray diffraction (WAXD). The penetration of cyclic molecules of a low-molecular-weight plasticizer with increased rigidity into the ordered regions of nitrocellulose has been experimentally established, and this penetration of plasticizer molecules is observed even at low concentrations. It is shown that the nature of interaction is the same for nitrocelluloses with nitrogen content of 12.0-12.1% and 13.0%.
