Abstract : It has been found that gossypol, a naturally occurring, readily available compound, can be used to increase the pot life of HTPB and other hydroxy terminated polymeric binder materials after a curative has been added. According to this invention, a good working range may be achieved by adding enough gossypol to produce a final propellant which contains on the order of from about 0.02 weight percent up to about 0.1 weight percent gossypol. However, it is not intended to limit the amount of gossypol used to the 0.02 to 0.1 weight percent range. A gossypol-acetic acid complex may also be used to increase pot-life, though the complex is not as effective as pure gossypol.
