Synthesis and Properties of 3‐Azido‐2,2‐bis(azidomethyl)propyl 2‐Azidoacetate: A Potential Azido Ester Plasticizer

This study reports the synthesis and characterization of a novel azido ester plasticizer, 3‐azido‐2,2‐bis(azidomethyl)propyl 2‐azidoacetate (ABAMPA), with good yield and high purity. The density, impact sensitivity, friction sensitivity, thermal decomposition temperature and glass transition temperature were determined to be 1.326 g ⋅ cm−3, 16 J, 324 N, 235.9 °C and −50.4 °C, respectively. The plasticizing effect of ABAMPA on glycidyl azide polymer (GAP) was calculated by molecular dynamics, the solubility parameter difference value was 1.7(J ⋅ cm−3)0.5, and the glass transition temperature of GAP was reduced from −35 °C to −43 °C when the weight ratio of ABAMPA and GAP was 50 : 50. The new azido ester exhibits high energy, remarkable thermostability and good compatibility with GAP, which indicates that it would have potential application in explosive and propellant formulations.
