초록

A body of gas generating material for a vehicle occupant protection device comprises about 40 to about 85 weight percent ammonium nitrate. The body of gas generating material also comprises an amount of a glycidyl azide polymer (GAP). The GAP is cured with a polyfunctional acrylate. The acrylate cured GAP can be used as a binder in the gas generating composition or as an energetic coating on tablets prepared from the composition. The acrylate cured GAP can also function as the sole fuel component in the gas generating composition, the composition being e...
