Explosive composition containing a hydroxyalkyl acrylate copolymer binder

Abstract

A readily castable explosive composition comprising (1) an explosive such RDX, HMX or perchlorate salts, (2) a readily curable elastomeric polymer such as a copolymer of 2,2-dinitropropyl acrylate, methyl acrylate and at least one member of the group 2-hydroxypropyl acrylate, 2-hydroxyethyl methacrylate, 2-hydroxypropyl methacrylate and 2-hydroxyethyl acrylate, (3) a diluent or plasticizer such as bis(2,2-dinitropropyl)formal and/or bis(2,2-dinitropropyl)acetal and (4) a cross-linking agent such as 2,4-toluene diisocyanate and polymethylene polyphenylisocyanate and optionally containing one or more of the following: fuels, stabilizers, antioxidants, polymerization catalysts and explosive desensitizers.
