Carborane Burning Rate Catalysts
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.
