ABSTRACT:
A solid rocket propellant composition having a relatively high low pressure deflagration limit (Pdl) and thereby capable of being extinguished with only a relatively small drop in combustion chamber pressure. The composition comprises a major amount of finely divided ammonium perchlorate and a minor amount of fluoroalkyl acrylate or methacrylate polymer as a binder, the weight ratio being from about 4.5:1 to about 6:1.The fluidity of the composition prior to curing can be improved by incorporating a small amount of an acrylate or methacrylate having an oxygen-containing functional group, e.g., hydroxyalkyl, epoxyalkyl and glycerol acrylates and methacrylates.
