ABSTRACT:
Metals such as copper and the transition elements may give rise to serious problems in conventional rubber based solid propellant binders. These metals may accelerate the curing action to such a degree that the pot life of the freshly mixed propellant is reduced. Also the metals may promote oxidative degradation of cured and uncured binder systems. These undesirable effects can be prevented by adding to the uncured binder certain binder soluble agents which are capable of forming stable complexes with the undesirable metals in which the valence of the metal ion is fixed. A wide variety of chelating agents can be used and include, particularly, the condensation products of salicylaldehyde with aliphatic di- and polyamines and with o-aminophenols.
