Abstract
The present invention lies in the field of compositions which modify the ballistic properties of solid propellants and in that of the double-base solid propellants containing these compositions. Various lead compounds are known to be effective in this function, but these compounds are toxic; the problem which is solved by the present invention is to replace these lead compounds with nontoxic compounds which furthermore do not impair other properties and the performance values of the propellants. The modifying compounds are chosen from the group consisting of .beta.-resorcylates and .gamma.-resorcylates. The invention also relates to processes for the synthesis of some of these products. Finally, it relates to double-base solid propellants containing these compounds.
