Abstract: Described herein is an improved cure catalyst, ferric-bis(acetylacetonato)oxinate, for urethane polymers derived form polyetherdiols and thiols, polybutadienediols and triols, polyesters and the like.

Abstract: This patent describes a novel desensitized explosive wherein a normally sitive solid explosive material is coated with an effective desensitizing amount of a phlegmatizing agent which contains functional groups reactive with one or more ingredients conventionally used in forming a thermally stable, crosslinked solid composite explosive. The present invention also includes thermally stable, crosslinked solid composite explosive in which said desensitized explosives are an integral part. Still further this invention includes the method of coating the as-received explosive material with said phlegmatizing agent, preferably in a drying vessel at elevated temperatures.

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.

Abstract: An inorganic perchlorate is sensitized by adding about 1-8 percent by wei of copper chromite to said perchlorate. The mixture of inorganic perchlorate-copper chromite can be used as a substitute for RDX.

Abstract: A sheet explosive employing a fine particle size filler in which a portion hereof is replaced by a plasticizer diluent providing castability at moderate temperatures while maintaining high rates of detonation. The material is crosslinked under mild conditions to eliminate thermoplasticity.
