9.5.10 Gas-Generating
Compositions
Gas-generating compositions are suitable for air
bags in cars systems. The gas must be nontoxic. The
gas-generating compositions must rapidly generate
gases upon combustion. Thermally stable nonazide
gas-generating composites are needed that have
acceptable burn rates and eject a relatively high
gas volume to solid particulate ratio at accept-
able flame temperatures [91,92]. For an extrudable
pyrotechnic composition poly(5-amino-1-vinylte-
trazole), poly(5-vinyltetrazole), poly(2-methyl-
5-vinyl)tetrazole, poly(1-vinyltetrazole), poly(3-
vinyl-1,2,5-oxadiazole), or poly(3-vinyl-1,2,4-tria-
zole), ...
