Abstract:

The propellant compositions of this invention are crosslinked with from about 0.1 to about 1.0 weight percent of nitrocellulose which improves the physical properties and the thermal stabilities of these propellants thereby permitting their storing and testing up to 165 F. These propellants employ additional ingredients which include one or more binder ingredients selected from the group consisting of polyglycol adipate PGA, polyethylene glycol PEG, polycapralactone PCL or PCP, and hydroxy-terminated polybutadiene HTPB plasticizer ingredients selected from the nitrate ester plasticizers consisting of nitroglycerin NG, trimethylol ethane trinitrate TMETN, triethylene glycol dinitrate TEGDN, and butane trioltrinitrate BTTN oxidizer ingredient selected from the group consisting of cyclotetramethylenetetranitramine HMX, cyclotrimethylenetrinitramine RDX, triaminoguanidine nitrate TAGN, and oxamide thermal stabilizers selected from the group consisting of 2-nitrodiphenylamine, 4-nitrodiphenylamine, n-methyl-p-nitroaniline, and resorcinol isocyanate curing agent carbon black additive and a modifying additive selected from ballistic additives and curing catalyst additives.
