Investigation of hydroxy terminated polybutadiene prepolymers which have been fractionated to increase their functionality has shown that they have a low crosslinking agent requirement for cure. This factor may be the limiting consideration in the application of these polymers to solid rocket propellants, because many of these prepolymers reach modulus values far in excess of acceptable when cured with a difunctional crosslinking agent. Those prepolymers that require a crosslinking agent for cure have been made into propellants. Author, modified-PL
