Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
74 words
A solid composite type propellant comprising in parts by weight of ammonium perchlorate, carboxy-modified polybutadiene, powdered aluminum, tris-(2-methylaziridinyl) phosphene oxide, a dibutylcarbitol formal plasticizer, to which is added as parts by weight in the percentage of 0.1 to 20 a ferrocene compound 1,3-diferrocenyl -1- butene which is of the structure Fc-R-Fc wherein Fc represents a ferrocene group and R is a radical selected from the group consisting of alkyl, cycloalkyl, alkenyl and cycloalkenyl radicals.
Claim 2
Dependent Claim
74 words
A solid composite type propellant comprising in parts by weight of ammonium perchlorate, carboxy-modified polybutadiene, powdered aluminum, tris-(2-methylaziridinyl) phosphene oxide, a dibutylcarbitol formal plasticizer, to which is added as parts by weight in the percentage of 0.1 to 20 a ferrocene compound 1,3-diferrocenyl -1- butene which is of the structure Fc-R-Fc wherein Fc represents a ferrocene group and R is a radical selected from the group consisting of alkyl, cycloalkyl, alkenyl and cycloalkenyl radicals.
Claim 3
Dependent Claim
72 words
A solid composite type propellant comprising in parts by weight of ammonium perchlorate, carboxy-modified polybutadiene, powdered aluminum, tris-(2-methylaziridinyl) phosphene oxide, a dibutylcarbitol formal plasticizer, to which is added as parts by weight in the percentage of 0.1 to 20 a ferrocene compound 1,7-diferrocenylheptone which is of the structure Fc-R-Fc wherein Fc represents a ferrocene group and R is a radical selected from the group consisting of alkyl, cycloalkyl, alkenyl and cycloalkyl radicals.
Claim 4
Dependent Claim
72 words
A solid composite type propellant comprising in parts by weight of ammonium perchlorate, carboxy-modified polybutadiene, powdered aluminum, tris-(2-methylaziridinyl) phosphene oxide, a dibutylcarbitol formal plasticizer, to which is added as parts by weight in the percentage of 0.1 to 20 a ferrocene compound 1,7-diferrocenylheptone which is of the structure Fc-R-Fc wherein Fc represents a ferrocene group and R is a radical selected from the group consisting of alkyl, cycloalkyl, alkenyl and cycloalkyl radicals.
Claim 5
Dependent Claim
53 words
A solid composite type propellant comprising in parts by weight of 66.10% ammonium perchlorate, 14.35% of a carboxy-modified polybutadiene, 12.00% of powdered aluminum, 0.55% of tris-(2-methylaziridinyl) phosphene oxide, 1.00% of a dibutylcarbitol formal plasticizer, to which is added as parts by weight in the percentage of 0.1 to 20 6.00% of 1, 3-diferocenyl-1-butene.
Claim 6
Dependent Claim
53 words
A solid composite type propellant comprising in parts by weight of 66.10% ammonium perchlorate, 14.35% of a carboxy-modified polybutadiene, 12.00% of powdered aluminum, 0.55% of tris-(2-methylaziridinyl) phosphene oxide, 1.00% of a dibutylcarbitol formal plasticizer, to which is added as parts by weight in the percentage of 0.1 to 20 6.00% of 1, 3-diferocenyl-1-butene.
Claim 7
Dependent Claim
19 words
A solid composite type propellant as in claim 3, wherein 1, 7-diferrocenylheptane may be substituted for the 1, 3-diferrocenyl-1-butene.
