Abstract : Carboranylmethyl alkyl sulfides are disclosed along with propellant compositions which employ the sulfides as plasticizers. The propellant compositions using the carboranylmethyl alkyl sulfides yield high burning rates and possess good physical properties at high and low temperatures. Processability of the propellants are good and the quality of the propellants are quite attractive. Representative of the carboranylmethyl alkyl sulfides (CB plasticizers) are carboranylmethyl ethyl sulfide (CMES), carboranylmethyl n-propyl sulfide (CMPS), carboranylmethyl n-butyl sulfide (CMBS), carboranylmethyl iso-butyl sulfide (CMIBS), and carboranylmethyl iso-propyl sulfide (CMIPS). Mixture and eutectic mixtures of the carboranylmethyl alkyl sulfides are also employed. Eutectic mixtures of CMPS and CMES (20 to 80%) yield very low-melting-point plasticizers which are very attractive for propellants subjected to low temperature environments. (Author)
