Gas generating composition

Abstract

There is provided a gas generating composition having good combustion performance. The gas generating composition comprises a fuel, an oxidizing agent and a binder, wherein the binder is at least one selected from polylactone compounds. Poly-ε-caprolactone is preferable as the polylactone compound, and the weight average molecular weight thereof is preferably in the range of 100 to 100,000.

1 . A gas generating composition comprising a fuel, an oxidizing agent and at least one binder selected from the group consisting of polylactone compounds, concentrations of ammonia and nitrogen dioxide being substantially 0 ppm in analysis results of a discharged gas after combustion of the composition.  
     
     
         2 . The gas generating composition as claimed in  claim 1 , wherein the weight average molecular weight of the polylactone compound is 100 to 100,000.  
     
     
         3 . The gas generating composition as claimed in  claim 1 , wherein the fuel is a nitrogen-containing organic compound, the oxidizing agent is an inorganic oxidizing agent, and the gas generating composition further comprises additives as necessary.  
     
     
         4 . The gas generating composition as claimed in  claim 2 , wherein the fuel is a nitrogen-containing organic compound, the oxidizing agent is an inorganic oxidizing agent, and the gas generating composition further comprises additives as necessary.  
     
     
         5 . The gas generating composition as claimed in  claim 1 , wherein the nitrogen-containing organic compound is at least one selected from the group consisting of guanidine nitrate, nitroguanidine, 5-aminotetrazole, dicyandiamide, azodicarbonamide, ammonium nitrate, melamine and glycine.
