Deflagration and migration properties of binuclear ferrocene compounds as deflagration modifiers in composite propellants

Abstract

Novel binuclear ferrocene derivs., with bulky ligands, were examd. as potential combustion modifiers in composite (ammonium perchlorate-hydroxy-terminated polybutadiene-based) propellants, esp. with respect to migration during storage. Of the ferrocene derivs. tested, Catocene migrated ∼30% more than 2,2'-bis(butylferrocenyl) propane of 1,1'-bis(ethylferrocenyl) pentane. The bulky ligand-contg. ferrocene derivs. had combustion activities similar to those of Catocene (at the 1.5 wt.% treating level), and had no effect on propellant workability and mech. properties.
