This invention pertains to solid propellants and more particularly to solid propellants of the composite type which contain a high energy plasticizer. One type of solid propellant which has been used in rocket motors is the so-called composite type and it generally comprises a solid oxidizer dispersed in an organic resin. In some cases it would be desirable to increase the impulse characteristics of these propellants by the use of a high ratio of energetic acidic plasticizer to organic resin but heretofore the use of such ratios has affected the compatibility of the propellant composition as evidenced by cure level, aging stability and plasticizer retention. Accordingly, it is an object of this invention to provide a solid propellant of a composite type containing a high energy acidic plasticizer. It is another object of this invention to provide a solid propellant which has a good plasticizer retention. It is a further object of this invention to provide a solid propellant with good aging stability. Author
