A synthesis of an energetic prepolymer used as a high-energy binder for an insensitive and high performance explosive is disclosed. More specifically, provided are a novel compound 2-nitratoethyl oxirane expressed by formula III, a novel compound poly(2-nitratoethyl oxirane) expressed by formula IV, obtained by polymerization of 2-nitratoethyl oxirane used as a monomer and a preparation method thereof. The compound, used as an energetic prepolymer and a monomer for preparation thereof can substitute for existing poly(glycidyl nitrate) (PGN) which has been known to be a promising one having the best performance among existing energetic prepolymers, but which has a problem to be self-decomposed after synthesis of polyurethane elastomer, to solve this problem
披露了一种用作不敏感和高性能炸药的高能预聚物的合成。更具体地,提供了一种由式III表示的新化合物2-硝基乙基环氧乙烷,一种由式IV表示的新化合物聚(2-硝基乙基环氧乙烷),通过将2-硝基乙基环氧乙烷用作单体进行聚合得到,并提供了一种制备方法。该化合物作为高能预聚物和用于其制备的单体可以替代已知为具有最佳性能的现有高能预聚物之一的聚(硝基甘油酸酯)(PGN),但在合成聚氨酯弹性体后存在自降解问题,以解决这一问题。
