Disclosed are novel compounds that can be used as an energetic binder used for improving the performance and the properties of a high explosive, and a preparation method thereof. More specifically, provided are glycidyl dinitropropyl formal of chemical formula IV having a nitro group (&#x2014;NO) as an energy group and having no hydrogen bonding to carbon to which the nitro group is binding, poly(glycidyl dinitropropyl formal) of chemical formula V polymerized using the glycidyl dinitropropyl formal as a monomer, and a preparation method thereof. 

Glycidyl dinitropropyl formal poly (glycidyl dinitropropyl formal) and preparation method thereof

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
