Abstract
Abstract A gas generant composition comprises between about 30 and about 85 wt. % of A) fuel, and between about 15 and about 70 wt % of B) oxidizer based on total weight of A) plus B). At least about 60 wt %, up to 100 wt % of the fuel A) comprises an nitrate salt of a polyamine of the general formula selected from the group consisting of: ##STR1## wherein in formulae (I)-(III) the Zs are the same or different and are selected from H and NH 2 , (IV) C 2 -C 3 -alkyl diamine, and mixtures thereof. At least about 60 wt %, up to 100 wt % of the oxidizer B) comprises basic copper(II) nitrate, i.e. Cu(NO 3 ) 2 .3Cu(OH) 2 and/or cobalt(III)triammine trinitrate, i.e., Co(NH 3 ) 3 .(NO 3 ) 3 .
