NIMMO及其聚合物的合成、性能及应用研究进展

摘要

The synthesis,properties and applications of 3-nitatomethyl-3-methyl oxetane (NIMMO) and its polymer (PNIMMO) are reviewed. With high energy, satisfied thermal stability and low mechanical sensitivity, PNIMMO can be used as a mature energetic binder in polymer bonded explosive(PBX) ,low vulnerability (LOVA) propellants and solid propellants. The low molecular weight linear polymers of PNIMMO can improve the mechanics characteristics of the binder system of PNIMMO in the condition of low temperature as plasticizer.%综述了3-硝酸酯甲基-3-甲基氧丁环(NIMMO)及其聚合物PNIMMO的合成、性能及应用研究进展.PNIMMO聚合物具有较高的能量水平、较好的热稳定性和优良的感度特性,是近年来发展起来的合成技术相对成熟的新型含能粘合剂之一,将其用于高能高聚物粘结炸药(PBX)、高能低易损(LOVA)发射药、高能固体推进剂中具有明显发展潜力.PNIMMO线性低分子齐聚物可作为增塑剂,可明显改善高分子PNIMMO粘合剂体系的低温力学性能.
