    • Polyethers containing pendant azide groups are cured without a catalyst byyclo-addition with diacetylenes to form triazole cross-linked, energetic binders having improved mechanical properties and stability. The polyethers typically have three hydroxy-terminated chains each of about 5000 to about 50,000 daltons. Ideally, only one azide group per chain reacts by cyclo-addition since the diacetylene is added in a proportion of about one molecule to each two polyether chains. Repeating units of glycidal azide, azidomethylmethyloxetane, bis-azidomethyloxetane/nitratomethylmethyloxetane, and bis-azidomethyloxetane/azidomethylmethyloxetane are believed effective as polyethers when used with the diethynlbenzenes 1,4-bis(ethynl)benzene, 1,4-bis(ethynlcarbonyl)benzene, and 1,3-bis(cyanoethynl)benzene. The polyethers may be further cross-liked at the hydroxyl terminations by urethane bonds.
    • 含有叠氮化物基团的聚醚通过与二乙炔进行环加成而不用催化剂固化,形成具有改善的机械性能和稳定性的三唑交联的高能粘合剂。 聚醚通常具有每个约5000至约50,000道尔顿的三个羟基封端的链。 理想情况下,每个链只有一个叠氮基团通过环加成反应,因为二乙炔以每一个聚醚链约1分子的比例加入。 当与二乙烯苯1,4-双(乙炔)苯,1,4-双(乙炔羰基)苯,二甲基亚氨基甲基苯,1,4-双(乙炔基)苯,二甲基甲硅烷基苯, 和1,3-双(氰乙炔)苯。 聚醚可以通过氨基甲酸酯键在羟基末端进一步交叉。

    • A flame inhibitor coating for application to those surfaces of a solid prllant grain in a rocket motor where burning is not desired such as the aft end of a perforated propellant grain which includes a barrier layer of a mixture of amine silane, a trialkoxypropylsilylamino prepolymer, and diglycidylether of polypropylene glycol, an epoxy applied to the grain surface and allowed to cure to a polysiloxane layer, and a flame inhibitor layer applied over the barrier layer consisting of a mixture of hydroxyl terminated polybutadiene and dimeryl diisocyanate with flake aluminum which is applied over the barrier layer and allowed to cure. The barrier layer prevents migration of nitrate esters from the solid propellant grain to the flame inhibitor layer thus preventing peeling and reduction of flame inhibiting properties. The polysiloxane barrier layer is also useful in itself as a flame inhibitor and can also be employed between the insulator/liner of the rocket motor and the solid propellant grain.
    • 用于火箭发动机的固体推进剂颗粒的那些表面的阻燃剂涂层,其中不需要燃烧,例如穿孔推进剂颗粒的后端,其包括胺硅烷,三烷氧基丙基甲硅烷基氨基预聚物和三烷氧基丙基甲硅烷基氨基预聚物的混合物的阻挡层和 聚丙二醇的二缩水甘油醚,施加到晶粒表面并使其固化成聚硅氧烷层的环氧树脂,以及施加在由羟基封端的聚丁二烯和二聚二异氰酸酯的混合物组成的阻挡层上的阻燃层, 阻挡层并允许固化。 阻挡层防止硝酸酯从固体推进剂颗粒向阻燃剂层迁移,从而防止阻燃性能的剥离和降低。 聚硅氧烷阻挡层本身也可用作阻燃剂,也可用于火箭发动机的绝缘体/内衬与固体推进剂颗粒之间。
