Abstract: New nitrogen-rich polymers, based on cellulose, were synthesized using common procedures. The point of interest was the introduction of tetrazole and nitramine moieties. The polymers were characterized by elemental analysis and vibrational spectroscopy (IR). The energetic properties were investigated using differential scanning calorimetry and bomb calorimetric measurements. Several detonation parameters, such as the detonation pressure, velocity, energy and temperature were computed using the EXPLO5 code. In addition, the sensitivities towards impact and friction were tested using the BAM drophammer as well as a friction tester.
