The commerically available R-45M hydroxy terminated polybutadiene HTPB prepolymer is being extensively studied for applications in highly loaded solid propellants. It has some deficiencies, however, in potlife control and in balancing mechanical properties at low and high temperatures, which presumably are caused by the materials low molecular weight, high functionality, and high reactivity of its functional groups. The report concerns a study to determine whether the available variations in ARCOs free radical polymerization process could produce a modified R-45M possessing superior characteristics for use in solid propellants. Pilot plant samples were studied.
