ABSTRACT:
This invention is first, a difunctional poly(glycidyl nitrate) oligomer (PGN oligomer), second, nitrated PGN oligomer and third, the use of the nitrated PGN oligomer as a plasticizer, particularly as a plasticizer for binders used in and/or as energetic formulations. Examples of energetic formulations are propellants, pyrotechnics and explosives and other such compositions. More particularly, this invention is a difunctional poly(glycidyl nitrate) oligomer of the formula ##STR1## where n is 0 to 3, having a M.sub.n of from about 304 to about 994. Another embodiment is the nitrated difunctional poly(glycidyl nitrate) oligomer of the formula ##STR2## where n is 0 to 3, having a M.sub.n of from about 394 to about 1084. This invention also comprises a plasticizer for binder compounds, namely, the nitrated PGN oligomer above; preferably the plasticizer above is used wherein the binder compound is used in energetic formulations; and preferably the binder compound is an energetic compound; more preferably the energetic formulation is selected from the group consisting of propellants, pyrotechnics and explosives.
