摘　　要：以聚3-硝酸酯甲基-3-甲基氧杂环丁烷(PNIMMO)和3-异氰酸丙烯为原料,二月桂酸二丁基锡为催化剂,合成端烯丙基氨酯聚3-硝酸酯甲基-3-甲基氧杂环丁烷(AUPNIMMO),将AUPNIMMO与四甲基对苯二腈氧化物(TTNO)通过缩合反应得到含异唑啉环的含能热塑性弹性体。采用傅里叶变换红外光谱仪、核磁共振氢谱仪、凝胶渗透色谱仪和差示扫描量热仪对产物的结构和性能进行了研究。结果表明,含能热塑性弹性体热稳定性良好(最大热分解峰峰温217.3℃),力学性能优异,拉伸强度为4MPa,延伸率为500%。Poly(3-nitrate)methyl-3-methyloxacyclobutane(AUPNIMMO)was synthesized by poly3-nitrate methyl-3-methyloxacyclobutane(PNIMMO)and propylene 3-isocyanate catalyzed by dibutyltin dilaurate.Then energetic thermoplastic elastomer(ETPE)with isoxazoline was synthesized by AUPNIMMO and tetramethyl-p-benzonitrile oxide(TTNO).The structure and properties of ETPE with isoxazoline were studied by FT-IR,1 H-NMR,GPC and DSC.The results shown that ETPE with isoxazoline exhibited good thermal stability(the temperature of exothermic peak at 217.3℃)and excellent mechanical properties,the tensile strength was 4MPa and the elongation was 500%.
