摘　　要：以三羟甲基丙烷为引发剂、三氟化硼·乙醚络合物为催化剂、3-硝酸酯甲基-3-甲基氧杂环丁烷(NIMMO)为单体,制备了三官能度的聚NIMMO(T-PNIMMO),随后在其端基共聚烯丙基缩水甘油醚(AGE),合成了烯基聚醚含能黏合剂(AGE-T-PNIMMO)。采用FTIR和NMR对产物进行了表征,并以四甲基对苯二腈氧化物(TTNO)为固化剂固化合成的烯基聚醚含能黏合剂制备出弹性体,考察了弹性体的力学和热性能。结果表明:该黏合剂具有低黏度(20℃黏度为8.93 Pa·s)、较低的玻璃化转变温度(-57.4℃)及可室温固化的特点;R(固化剂TTNO的腈氧基团与AGE-T-PNIMMO双键的物质的量之比,下同)=1.0时,得到的弹性体拉伸强度最高可达0.80 MPa,分解峰峰温为202℃。The tri-functional poly(3-nitratomethyl-3-methyloxetane)(T-PNIMMO) was synthesized using trimethylolpropane as initiator, boron trifluoride ether complex as catalyst, and 3-nitric ester methyl-3-methoxycyclobutane(NIMMO) as monomer. Then, the copolymerization of T-PNIMMO and allyl glycidyl ether(AGE) led to alkenyl polyether energetic binder(AGE-T-PNIMMO). The product was characterized by FTIR and NMR. Subsequently, the mechanical properties and thermal properties of elastomer prepared after curing with tetramethyl-terephthalobisnitrile oxide(TTNO) were investigated. The results show that the energetic binder has low viscosity(20 ℃, 8.93 Pa·s), low glass transition temperature(Tg)(-57.4 ℃), and can be cured at room temperature. When R value(molar ratio of nitrile oxygen group of TTNO to double bond of AGE-T-PNIMMO) was 1.0, the tensile strength and thermal decomposition peak temperature of the elastomer were 0.80 MPa and 202 ℃.
