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.
