Disclosed are glycidyl di-nitropropyl carbonate and poly(glycidyl di-nitropropyl carbonate) which is prepolymer used as an energetic binder for an insensitive and high performance explosive. The present invention introduces the nitro group instead of the nitrate group, thereby enabling to provide the prepolymer having the high thermal stability (thermal decomposition initiating temperature of at least 200&deg; C. or higher) more excellent than that of the conventional energy binder.

Glycidyl di-nitropropyl carbonate and poly (glycidyl di-nitropropyl carbonate)

Energetic plasticizer comprising eutetic mixture of bis (2,2-dinitropropyl) formal, 2,2-dinitropropyl 2,2-dinitrobutyl formal and bis (2,2-dinitrobutyl) formal, and preparation method thereof

The present invention provides an energetic plasticizer comprising bis(2,2-dinitropropyl) formal and a material that keeps bis(2,2-dinitropropyl) formal from crystallizing out, wherein the material that keeps bis(2,2-dinitropropyl) formal from crystallizing out is bis(2,2-dinitropropyl) diformal. In case where BDNPDF is used to prevent BDNPF from crystallizing out, BDNPF is not crystallized even though it stands at the temperature &minus;20&deg; C. for more than 6 months, while its thermal and chemical properties are similar to that of conventional plasticizers. Also, by using BDNPDF, that has been considered as a unfavorable side product, as an inhibitor of crystallization, no additional process is required to remove BDNPDF. Moreover, the cost involved is lower.
