ABSTRACT:
A selected polybromocompound, when added in an amount from about 1.0 to at 3.0 weight percent to a controllable solid propellant composition, is effective as a reignition suppressant without having detrimental effects on the ballistic properties of the propellant. The mechanism for accomplishing these desired results consists of sweeping away the combustible exhaust products from the propellant's extinguished surface by the non-combustible decomposition gases of a polybromocompound which is selected from diammonium tetrabromophthalate, tetrabromophthalimide, and N-substituted tetrabromophthalimide.
