ABSTRACT:
Polybutadiene-iron carbonyl complexes are useful as the binder-catalyst for ast-burning rate propellants which are additionally comprised of ammonium perchlorate, aluminum powder, curative-cross-linking agent, and additive (e.g., wetting agents, grinding aids, etc.). The complexes, which are regarded as copolymers of uncomplexed polybutadiene and tricarbonyl(diene)-iron units [C.sub.8 H.sub.12 Fe(CO).sub.3 ].sub.x (where x is one or multiples of one), can be utilized as a high burning rate additive or as a plasticizer for carboxylated polybutadiene binder materials, such as, polybutadiene acrylic acid, polybutadiene acrylic acid-acrylonitrile, carboxyl-terminated polybutadiene, and hydroxy- or epoxy-terminated polybutadiene. The various binder materials, such as those set forth above, can be reacted with the polycarbonyl-iron directly to yield a prepolymer which can be used as the binder-catalyst for propellants containing, an oxidizer, metal fuel, curative-cross-linking agent, and additives.
