Abstract

Gas generant compositions comprised of a high nitrogen content solid and annergetic polymer, which release high levels of nitrogen and minimum levels of toxic and flammable gases.

Claims

1. A composition of matter for use as a gas generant comprising:

a high nitrogen content solid selected from the group consisting of;

ammonium 5-nitraminotetrazole, triaminoguanidinium 5-nitraminotetrazole, aminoguanidinium 5,5'"'"'-bitetrazole and guanidinium 5,5'"'"'-bitetrazole; and

an energetic polymer selected from the group consisting of;

a copolymer of 3,3-bis(azidomethyl) oxetane and 3-azidomethyl-3-methyloxetane, and a copolymer of 3,3-bis(azidomethyl) oxetane and 3-nitratomethyl-3-methyloxetane.

2. The composition of claim 1 wherein said high nitrogen content solid and said energetic polymer are present in about a 50:

50 by weight ratio.

3. The composition of claim 1 which further comprises a curative, the biuret trimer of hexamethylene diisocyanate.

4. The composition of claim 1 which further comprises a catalyst, dibutyltin dilaurate.

5. A composition of matter for use as a non-condensable gas generant comprising:

about 50 percent by weight of a high nitrogen content solid selected from the group consisting of;

ammonium 5-nitraminotetrazole, triaminoguanidinium 5-nitraminotetrazole, aminoguanidinium 5,5'"'"'-bitetrazole and guanidinium 5,5'"'"'-bitetrazole;

about 50 percent by weight of an energetic polymer selected from the group consisting of;

a copolymer of 3,3-bis (azidomethyl) oxetane and 3-azidomethyl-3-methyloxetane, and a copolymer of 3,3-bis(azidomethyl) oxetane and 3-nitratomethyl-3-methyloxetane;

buret trimer of hexamethylene diisocyanate curative; and

dibutyltin dilaurate catalyst.
