Abstract
Abstract An improved energetic propellant charge, of the solid type useful in rockets and rocket motors, may be formulated with a system of the polymer of tetrakis(difluoramino)amyl acrylate and a large amount of hexakis(difluoramino)propyl ether if trimethylolpropane trimethacrylate and a peroxidic polymerization catalyst such as dichlorobenzoyl peroxide are used to crosslink the tetrakis(difluoramino)amyl acrylate from which the polymer is derived.
