Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
38 words
A propellant composition comprising; an oxidizer including bis[N-(trinitroethyl)nitramino]ethane, an acrylate-acrylic acid binder, and a curing agent, said acrylate-acrylic acid being present in a ratio of acrylate to acrylic acid in an amount of about 90/10 to about 96/4.
Claim 2
Dependent Claim
38 words
A propellant composition comprising; an oxidizer including bis[N-(trinitroethyl)nitramino]ethane, an acrylate-acrylic acid binder, and a curing agent, said acrylate-acrylic acid being present in a ratio of acrylate to acrylic acid in an amount of about 90/10 to about 96/4.
Claim 3
Dependent Claim
13 words
The propellant composition of claim 1, wherein said oxidizer also includes ammonium perchlorate.
Claim 4
Dependent Claim
23 words
The propellant composition of claim 1, wherein said curing agent is diepoxy dicyclohexyl carboxylate, and said propellant composition further comprises a plasticizer, 1,2,3-tris[1,2-bis(difluoroamino)ethoxy]propane.
Claim 5
Dependent Claim
29 words
The propellant composition of claim 1, wherein said binder consists of a copolymer of acrylate-acrylic acid in an amount up to about 25 weight percent of the propellant composition.
Claim 6
Dependent Claim
37 words
The propellant composition of claim 1, wherein said curing agent is diepoxy dicyclohexyl carboxylate, and said propellant composition further comprises a plasticizer, 1,2,3-tris[1,2-bis(difluoroamino)ethoxy]propane, said binder to plasticizer being present in a ratio of about 1 to 5.
Claim 7
Dependent Claim
40 words
The propellant composition of claim 5, wherein said plasticizer and binder constitute from about 25 to about 35 weight percent of the propellant composition, and said oxidizer constitutes from about 65 to about 75 weight percent of said propellant composition.
Claim 8
Dependent Claim
14 words
The propellant composition of claim 6, wherein said acrylate-acrylic acid is ethyl acrylate-acrylic acid.
Claim 9
Dependent Claim
93 words
The propellant composition of claim 1, wherein said oxidizer consists of ammonium perchlorate of about 19.2 weight percent of the propellant composition and bis[N-(trinitroethyl)nitramino]ethane of about 48.6 weight percent of the propellant composition, said curing agent consists of diepoxy dicyclohexyl carboxylate of about 1.4 weight present of the propellant composition, and the propellant composition contains the additional ingredients carbon black in an amount of about 0.5 weight percent of the propellant composition, and a plasticizer, 1,2,3-tris[1,2-bis(difluoroamino)ethoxy]propane, of about 25.7 weight percent of the propellant composition, the remainder of said propellant composition being binder.
Claim 10
Dependent Claim
77 words
