NITRATOETHYL OXIRANE, POLY(2-NITRATOETHYL OXIRANE) WHICH ARE USEFUL AS ENERGETIC PREPOLYMERS AND PREPARATION METHOD THEREOF

摘要

PURPOSE: Nitratoethyl oxirane, poly(2-nitratoethyl oxirane) and a preparation method thereof are provided, which compounds have similar energy to PGN(polyglycidylnitrate) and improved storage stability. Therefore, they can be useful as energetic prepolymers. CONSTITUTION: The 2-nitratoethyl oxirane is represented by the formula (III). The poly(2-nitratoethyl oxirane) is represented by the formula (IV). The method for preparing the poly(2-nitratoethyl oxirane) of the formula (IV) comprises the steps of: preparing 1,4-dinitrato-2-butanol of the formula (II) from 1,2,4-butanetriol of the formula (I); preparing 2-nitratoethyl oxyran of the formula (III) from 1,4-dinitrato-2-butanol of the formula (II); and polymerizing the 2-nitratoethyl oxyran of the formula (III).
