Abstract : Unsaturated polymers such as polybutadienes and polyurethanes are frequency used as propellant binders. Ferrocene has frequently been used as a burning rate modifier in those propellants. Ferrocene, however, tends to migrate within the propellants, resulting in an uneven distribution of ferrocene and thus uneven burning of the propellant. This problem will be eliminated if the ferrocene is bound in some way to the polymer backbone of the propellant binder. Accordingly, one object of this invention is to provide novel compounds. Another object of this invention is to provide pure ferrocene thiols. A further object of this invention is to provide a means for preventing burning rate modifiers from migrating in propellants.
