    • A composition consisting essentially of a polyphosphazene binder having the following repeating units: ##STR1## wherein n is from about 20 to about 50,000, A is selected from --O-- and --NH--, and R.sup.1 and R.sup.2 are independently selected from alkyl having from one to about 20 carbon atoms, aryl having from 6 to about 14 carbon atoms, alkaryl having from 7 to about 30 carbon atoms, any of the preceding moieties substituted with halogen, hydroxyl, alkoxy, aryloxy, or nitro groups, or any of the preceding moieties linked by ether or amine linkages. Combined with an organic fiber filler, this material provides an erosion resistant insulation composition for temporarily protecting the interior of a rocket motor combustion chamber from thermal damage while the rocket is firing. Provided as a barrier coating or layer between the propellant grain and other structures within a rocket motor, this material prevents migration of plasticizers, nitrate esters, and other fluid or mobile ingredients from the propellant grain.
    • 基本上由具有以下重复单元的聚磷腈粘合剂组成的组合物:其中n为约20至约50,000,A选自-O-和-NH-,并且R 1和R 2独立地选自具有 1至约20个碳原子,具有6至约14个碳原子的芳基,具有7至约30个碳原子的烷芳基,任何前述部分被卤素,羟基,烷氧基,芳氧基或硝基取代,或任何 前述部分通过醚或胺键连接。 结合有机纤维填料,该材料提供耐腐蚀绝缘组合物,用于在火箭发射时临时保护火箭发动机燃烧室内部免受热损伤。 作为火箭发动机内的推进剂颗粒和其他结构之间的阻隔涂层或层,该材料防止增塑剂,硝酸酯和其它流体或可移动成分从推进剂颗粒中迁移。

    • A formulation is provided which is capable of performing as a liner layer between a rocket motor casing and the propellant grain disposed within the interior of the rocket motor casing. The composition produces relatively little smoke during the operation of the rocket motor and is capable of securely bonding a wide range of conventional propellants to a wide range of conventional casings. In one preferred formulation, the liner consists of from from about 50% to about 75% oxygen containing polymer; from about 3% to about 15% curing agent; from about 5% to about 50% filler and from about 0.01% to about 0.5% cure catalyst.
    • 提供了能够在火箭发动机壳体和设置在火箭发动机壳体内部的推进剂颗粒之间作为衬垫层的配方。 该组合物在火箭发动机操作期间产生相对较少的烟雾,并且能够将广泛范围的常规推进剂牢固地粘合到各种常规壳体上。 在一个优选的制剂中,衬垫由约50%至约75%的含氧聚合物组成; 约3%至约15%的固化剂; 约5%至约50%的填料和约0.01%至约0.5%的固化催化剂。
