A new energetic glycidyl-based polymer containing nitramine groups (glycidyl nitramine polymer, GNAP) was synthesized using glycidyl azide polymer (GAP) as the starting material. The synthesis involved Staudinger azide-amine conversion, followed by carbamate protection of the amino group, nitration with nitric acid (100%) and trifluoroacetic anhydride and was concluded by deprotection with aqueous ammonia. The products obtained were characterized by elemental analysis and vibrational spectroscopy (IR). The energetic properties of GNAP were determined using bomb calorimetric measurements and calculated with the EXPLO5 V6.02 computer code, showing better values regarding the energy of explosion (ΔEU = −4813 kJ kg−1), the detonation velocity (VDet = 7165 m•s−1), as well as the detonation pressure (pCJ = 176 kbar), than the comparable polymers GAP and polyGLYN. The explosion properties were tested by impact sensitivity (IS), friction sensitivity (FS), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and electrostatic discharge (ESD) equipment. The results revealed GNAP to be insensitive towards friction and electrostatic discharge, less sensitive towards impact (40 J) and a decomposition temperature (170 °C) in the range of polyGLYN.
