Insensitive explosive compositions were prepared by reacting di-isocyanate and/or poly-isocyanate monomers with an explosive diamine monomer. Prior to a final cure, the compositions are extrudable. The di-isocyanate monomers tend to produce tough, rubbery materials while polyfunctional monomers (i.e. having more than two isocyanate groups) tend to form rigid products. The extrudable form of the composition may be used in a variety of applications including rock fracturing.

1. A method for extending a fracture network in rock, comprising: inserting an extrudable insensitive explosive composition into fissures in rock, the composition comprising an insensitive explosive reaction product of a reaction between an explosive diamine monomer and a monomer selected from an alkyl di-isocyanate monomer, an aryl di-isocyanate monomer, an alkyl poly-isocyanate monomer, an aryl poly-isocyanate monomer, or mixtures thereof, and thereafterdetonating the composition, thereby extending the fracture network in the rock. 2. The method of claim 1, further comprising a step of curing the composition prior to detonating the composition. 3. The method of claim 1, wherein the explosive diamine monomer is 3,3′-diamino-4,4′-azoxyfurazan. 4. The method of claim 1, wherein the extrudable insensitive explosive composition further comprises a glycidyl azide polymer, hydroxyl-terminated polybutadiene, or mixtures thereof. 5. The method of claim 1, wherein the aryl di-isocyanate monomer is selected from 4-di-isocyanato-1-methyl-benzene, 1-isocyanato-4-[(4-isocyanatophenyl)methyl]benzene, 1-isocyanato-2-[(2-isocyanatophenyl)methyl]benzene, 1-isocyanato-2-[(4-isocyanatophenyl)methyl]benzene, or di-isocyanato-containing isomers thereof. 6. The method of claim 1, wherein the di-isocyanate monomer is 3-isocyanatomethyl-3,5,5-trimethylcyclohexyl-di-isocyanate. 7. The method of claim 1, wherein the insensitive explosive composition is a product of a chemical reaction of 4,4′diamino-3,3′-azoxyfurazan with a di-isocyanate monomer selected from 3-isocyanatomethyl-3,5,5-trimethylcyclohexyl-di-isocyanate, 2,4-diisocyanato-1-methyl benzene, 1-isocyanato-4-[(4-isocyanatophenyl)methyl]benzene, 1-isocyanato-2-[(2-isocyanatophenyl)methyl]benzene, and 1-isocyanato-2-[(4-isocyanatophenyl)methyl]benzene. 8. The method of claim 1, wherein the insensitive explosive composition is a product of a chemical reaction of an explosive diamine monomer, a glycidyl azide polymer, and an isocyanate-containing monomer selected from a di-isocyanate monomer, a poly-isocyanate monomer, or mixtures thereof. 9. The method of claim 1 wherein the insensitive explosive reaction composition is a product of a chemical reaction of 4,4-diamino-3.3′-azoxyfurazan monomer and a monomer selected from a di-isocyanate monomer, a poly-isocyanate monomer, or mixtures thereof.
