Abstract:

New carborane burning rate catalysts designed for use in solid propellants, without the problems associated with current catalysts, have been prepared. High molecular weight, non-volatile derivatives of bis-1- carboranylmethyl ether were synthesized and evaluated for compatibility in hydroxy terminated polybutadiene HTPB binders as well as compatibility and ballistic properties in aluminized HTPB-UFAP propellants. The introduction of unsaturation and branched unsaturation into the side chain of bis-carborane derivatives has provided carboranes which are compatible with HTPB binders at high levels and also exhibit a wide liquid range. Thus, undecylenyl-bis-1- carboranylmethyl ether was compatible with cured HTPB at the 50 level after storage for six weeks at 77F. The compound 3,7-dimethyl-2,6-octadienyl-bis-1- carboranylmethyl ether has exhibited compatibility with cured HTPB at the 57 level.
