Abstract
Abstract An improved explosive composition is disclosed and comprises a major portion of an explosive having a detonation velocity between about 1500 and 10,000 meters per second and a minor amount of a getter additive comprising a compound or mixture of compounds capable of capturing or deactivating free radicals or ions under mechanical or electrical shock conditions and which is not an explosive. Exemplary getter additives are isocyanates, olefins and iodine.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
100 words
A composition of matter comprising: (1) a major portion of a metastable explosive capable of being detonated by a mechanical, thermal or electrical shock and having a detonation velocity from 1,500 to 10,000 meters per second, and (2) from 0.1 to 20 weight percent of a getter additive, or combination of getter additives, which is (i) capable of capturing or deactivating free radicals or ions during the initiation of said explosive, (ii) not an explosive, and (iii) is selected from the group consisting of C 4 to C 32 isocyanates, C 2 to C 30 olefins, iodine, or mixtures thereof.
Claim 2
Dependent Claim
100 words
A composition of matter comprising: (1) a major portion of a metastable explosive capable of being detonated by a mechanical, thermal or electrical shock and having a detonation velocity from 1,500 to 10,000 meters per second, and (2) from 0.1 to 20 weight percent of a getter additive, or combination of getter additives, which is (i) capable of capturing or deactivating free radicals or ions during the initiation of said explosive, (ii) not an explosive, and (iii) is selected from the group consisting of C 4 to C 32 isocyanates, C 2 to C 30 olefins, iodine, or mixtures thereof.
Claim 3
Dependent Claim
19 words
The composition defined in claim 1 wherein said getter additive has a molecular weight between about 125 and 800.
Claim 4
Dependent Claim
21 words
