5. In a solid rocket propellant grain comprising a fuel, oxidizer and binder the improvement which comprises a binder consisting essentially of a relatively non-volatile high nitrogen hydrazine substituted plasticizer material and a hydrophilic polymer, said plasticizer material being liquid at the temperature of formulating said composition and said hydrophilic polymer yielding an extensible, elastic material when blended with said plasticizer, the relative proportions of said plasticizer and said polymer ranging from about 15/1 to 1/3 on a weight basis, said binder being from about 10 to about 60 weight percent of the total propellant gain.
