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
这项研究报告了一种新型叠氮基酯增塑剂3-叠氮基2,2-双(叠氮基甲基)丙基2-叠氮基乙酸酯(ABAMPA)的合成和表征,具有良好的收率和高纯度。测得的密度,冲击敏感性,摩擦敏感性,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。通过分子动力学计算ABAMPA对缩水甘油基叠氮化物聚合物(GAP)的增塑作用,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°C降低至-当ABAMPA与GAP的重量比为50:50时为43°C。这种新型叠氮基酯具有高能量,出色的热稳定性以及与GAP的良好相容性,
