Three linear diazido compounds as novel binders have been prepared via a one-step substitution of corresponding bromo-ended halide. The structures of these novel diazido compounds and their reactivity with alkyne have been characterized by FTIR, ¹H NMR, ¹³C NMR, GPC, and element analysis. Polytriazolepolyethyelene oxide-tetrahydrofuran (PTPET) elastomers are prepared by curing alkyne terminated polyethyleneoxide-tetrahydrofuran (ATPET) with glycidyl azide polymer (GAP) and three novel diazido compounds at different molar ratios of -N₃ to alkyne. The properties of the PTPET elastomers are measured by TGA, DSC and mechanical apparatus. Plasticizer A3 [1:1 mixture of bis-(2,2-dinitropropy) acetal (BDNPA) and bis-(2,2-dinitropropyl)] is added thereafter as a comparison. The results revealed that PTPET elastomers synthesized with the novel compounds that have longer -CH₂ chain and ether group could have better properties and serve as promising binders for propellant components.

三种二叠氮化合物的简便合成及其在聚醚聚三叠氮弹性体中作为固体推进剂粘合剂的应用

通过一步取代相应的溴封端卤化物，制备了三种作为新型粘合剂的线性二叠氮化合物。这些新型二叠氮化合物的结构及其与炔烃的反应性已通过 FTIR、¹ H NMR、¹³ C NMR、GPC 和元素分析进行表征。聚三唑聚环氧乙烷-四氢呋喃 (PTPET) 弹性体是通过将炔封端的聚环氧乙烷-四氢呋喃 (ATPET) 与缩水甘油基叠氮化物聚合物 (GAP) 和三种不同摩尔比 -N _{3 的}新型二叠氮化合物固化制备的到炔烃。PTPET 弹性体的性能通过 TGA、DSC 和机械设备进行测量。随后加入增塑剂A3[双-(2,2-二硝基丙基)缩醛(BDNPA)和双-(2,2-二硝基丙基)的1:1混合物]作为比较。结果表明，用具有更长-CH ₂链和醚基团的新型化合物合成的PTPET弹性体具有更好的性能，可作为推进剂组分的有前途的粘合剂。
