Claim 1
Independent Claim
61 words
A propellant comprising, by weight: (A) a polymeric binder system, in the range 8-35 percent; (B) curing agents, in the range 0-10 percent; (C) plasticizing agents, in the range 0-25 percent; (D) a composition having the general formula x[(NHNH.sub.2).sub.3 CNO.sub.3 ].(1-x)[((NHNH.sub.2).sub.3 C) .sub.2 B.sub.10 H.sub.10 ] wherein the value of x is between 0.01 and 0.99, in the range 35-90 percent.
Claim 2
Dependent Claim
61 words
A propellant comprising, by weight: (A) a polymeric binder system, in the range 8-35 percent; (B) curing agents, in the range 0-10 percent; (C) plasticizing agents, in the range 0-25 percent; (D) a composition having the general formula x[(NHNH.sub.2).sub.3 CNO.sub.3 ].(1-x)[((NHNH.sub.2).sub.3 C) .sub.2 B.sub.10 H.sub.10 ] wherein the value of x is between 0.01 and 0.99, in the range 35-90 percent.
Claim 3
Dependent Claim
33 words
A propellant according to claim 1 wherein further said composition is a coprecipitate and the substituents B 10 H 10 -2 and NO 3 - are intimately intertwined through interlattice and intercrystalline mixing.
Claim 4
Dependent Claim
