报道了一种新型叠氮酯类增塑剂2-叠氮基乙酸3-叠氮基-2，2-双（叠氮甲基）丙酯（ABAMPA）的合成与表征。测得其密度、撞击感度、摩擦感度、热分解温度和玻璃化转变温度分别为1.326 g·cm-3、16 J、324 N、235.9 °C和-50.4 °C。用分子动力学方法计算了ABAMPA对叠氮缩水甘油醚聚合物（GAP）的增塑作用，当ABAMPA与GAP的质量比为50：50时，溶解度参数差值为1.7（J·cm-3）± 0.5，GAP的玻璃化转变温度从-35 ℃降低到-43 ℃。新型叠氮酯具有高能量、显着的热稳定性以及与GAP良好的相容性，表明其在炸药和推进剂配方中具有潜在的应用前景。
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.
