Abstract: The copolymers of vinyl ferrocene (VF) and butadiene are disclosed along with preparative procedures therefor. The copolymers are produced in an organic solvent when polymerization is initiated by an azo type initiator selected from the initiators consisting of azo-bis-(2-methyl-hydroxyvaleronitrile), azo-bis-(hydroxyethyl-2-methyl proprionate), and azo-bis-(2-methyl-3-hydroxy proprionitrile). The copolymers serve as a binder for solid propellant compositions and also serve to increase the burning rate of solid propellants wherein used.

Abstract: High energy propellants of low sensitivity in the range of class 2 military explosives and propellants are disclosed. The propellants are comprised of acrylic copolymers, nitrate ester plasticizers, metallic fuel, inorganic oxidizer, and curatives. The acrylic copolymers are constituted of acrylic acid copolymerized with a nitrated acrylate selected from petrin acrylate and 2,2-dinitropropyl acrylate. The nitrate ester plasticizers are selected from triethylene glycol dinitrate, (TEGDN), trimethylolethane trinitrate, (TMETN), and butane-triol trinitrate, (BTTN). The metallic fuel is powdered aluminum, and the inorganic oxidizer is ammonium perchlorate. A commercially available diepoxide, such as dicyclo diepoxy carboxylate, is used as a curing agent. Compatible cross-linking catalyst such as ferric acetylacetonate may be used to decrease the curing time and/or temperature.
