ABSTRACT:
A plasticizer-free propellant for inflating passenger airbags in vehicles mprising from about 78 to about 90 weight percent of cyclotrimethylenetrinitramine (RDX) and from about 10 to about 22 weight percent of a plasticizer-free polymer binder formed by curing a mixture of a polyoctenamer and a polymer comprising an acrylate polymer or a methacrylate polymer having a glass transition temperature of -30.degree. C. or lower and 0.01 to 5 weight percent based on the total amount of the monomers, of a crosslinking monomer having two or more double bonds of substantially the same reactivity in the molecule or one double bond and a crosslinking functional group such as an epoxide ring, a hydroxyl group, or a carbonyl group. This propellant is useful in hybrid inflators for air/safety bags in vehicles.
