Abstract
Abstract This invention relates to self-supporting, water-resistant explosive compositions composed essentially entirely of explosively active ingredients and methods for making same. The compositions consist essentially of a particulate high explosive and a high viscosity nitrocellulose binder plasticized with TMETN (trimethylolethane trinitrate) without the use of other plasticizers.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
94 words
A self-supporting, high powered, brisant, explosive composition composed essentially entirely of explosive ingredients and consisting essentially of: a. 46 to 87% by weight of a finely divided explosive selected from the group consisting of cyclotrimethylenetrinitramine, cyclotetramethylenetetranitramine, and pentaerythritol tetranitrate, and mixtures thereof having an average particle size not greater than about 25 microns; b. 1 to 4% by weight of explosive, high-viscosity, nitrocellulose binder; and c. 12 to 49% by weight of the liquid explosive plasticizer trimethylolethane trinitrate, the ratio of said plasticizer to said nitrocellulose being in the range of 6.5/1 to 15/1.
Claim 2
Dependent Claim
94 words
A self-supporting, high powered, brisant, explosive composition composed essentially entirely of explosive ingredients and consisting essentially of: a. 46 to 87% by weight of a finely divided explosive selected from the group consisting of cyclotrimethylenetrinitramine, cyclotetramethylenetetranitramine, and pentaerythritol tetranitrate, and mixtures thereof having an average particle size not greater than about 25 microns; b. 1 to 4% by weight of explosive, high-viscosity, nitrocellulose binder; and c. 12 to 49% by weight of the liquid explosive plasticizer trimethylolethane trinitrate, the ratio of said plasticizer to said nitrocellulose being in the range of 6.5/1 to 15/1.
Claim 3
Dependent Claim
96 words
A self-supporting, high powered, brisant, flexible, explosive composition composed essentially entirely of explosively active ingredients and consisting essentially of: a. 46 to 70% by weight of a finely divided explosive selected from the group consisting of cyclotrimethylenetrinitramine, cyclotetramethylenetetranitramine and pentaerythritol tetranitrate, and mixtures thereof having an average particle size not greater than about 25 microns; b. 3 to 4% by weight of explosive, high-viscosity, nitrocellulose binder; and c. 33 to 49% by weight of the liquid explosive plasticizer trimethylolethane trinitrate, the ratio of said plasticizer to said nitrocellulose being in the range of 9/1 to 15/1.
Claim 4
Dependent Claim
96 words
A self-supporting, high powered, brisant, flexible, explosive composition composed essentially entirely of explosively active ingredients and consisting essentially of: a. 46 to 70% by weight of a finely divided explosive selected from the group consisting of cyclotrimethylenetrinitramine, cyclotetramethylenetetranitramine and pentaerythritol tetranitrate, and mixtures thereof having an average particle size not greater than about 25 microns; b. 3 to 4% by weight of explosive, high-viscosity, nitrocellulose binder; and c. 33 to 49% by weight of the liquid explosive plasticizer trimethylolethane trinitrate, the ratio of said plasticizer to said nitrocellulose being in the range of 9/1 to 15/1.
