THE DEVELOPMENT AND EVALUATION OF A HYDROCARBON BINDER FOR HIGH ENERGY SOLID PROPELLANTS,
Abstract
The acquisition and characterization of hydroxy terminated, Telagen S prepolymers was continued. Prepolymers of high (2500) and low (1000) molecular weights and a prepolymer of 60 percent saturation were investigated. Except for the characteristics pointed out above, these prepolymers resembled those investigated previously. Esterification rates with propionic acid indicate that the hydroxy groups of Telagen S are of the same reactivity as those of 2-octanol. The major factor influencing the low temperature behavior of saturated binders and propellants is the degree of saturation. The effect of prepolymer molecular weight was less important. Investigations included effect of pendant ethyl content, dilatometry of binders, pour points of prepolymers, gel particles in prepolymers, and differential thermal analysis. The low temperature behavior of Telagen S propellants generally confirmed the influence of saturation and of prepolymer molecular weight. A number of carboxylic anhydrides and of isocyanate reactions were investigated as possible curing systems for HAP propellants. Propellant studies indicate that a HAP propellant based on Carwinate M-125 as a curing agent may be feasible. Aging studies indicate that moisture is detrimental to the stability of Minuteman Wing VI second-stage and Telagen S propellants. The effect is more pronounced at higher temperature. (Author)
