Nitrate ester plasticized energetic compositions, method of making and rocket motor assemblies containing the same

A nitrate ester plasticized energetic composition in which the binder is made of, prior to curing, lower alkylene glycol prepolymer blocks end-capped with ethylene glycol monomers and/or oligomers. The end-capped prepolymer blocks are preferably difunctional or trifunctional. The lower alkylene glyc...

More Information
Summary:A nitrate ester plasticized energetic composition in which the binder is made of, prior to curing, lower alkylene glycol prepolymer blocks end-capped with ethylene glycol monomers and/or oligomers. The end-capped prepolymer blocks are preferably difunctional or trifunctional. The lower alkylene glycol are preferably propylene glycol, butylene glycol, and/or copolymers thereof. The difunctional end-capped alkylene glycol prepolymer blocks are cured with a diisocyanate or polyisocyanate. In the case of a trifunctional (or higher functional) end-capped alkylene glycol prepolymer block, preferably a diisocyanate is used to effect crosslinking.
