characteristics while avoiding problems such as ammonia production encountered with conventional bonding agents as discussed briefly above bonding agents are used to link solid particles to the polymer bonding system of a propellant thus improving the stress and strain properties of the propellant the present invention teaches the attachment of a polar moiety imine to the overall organic molecular structure such as a jeffamine structure it is presently believed that the imine then attracts and aligns with the ammonium perchlorate by means of an electrostatic interaction this is accomplished by the nature of the schiff base i e the c u2550 n group has partial charges u03b4 u03b4 which are sufficient to align with the polar ammonium perchlorate molecule in addition the conversion of the amine to an imine substantially eliminates the problem of ammonia production in the formulation of propellants the compounds of the present invention also include hydroxyl functionality the hydroxyl functionality provides a mechanism for incorporation of the bonding agent and solid ammonium perchlorate within the binder matrix the hydroxyl functionality reacts with the conventional isocyanate curative used in such propellant formulations thus it is possible to incorporate large quantities of solids into the binder while still maintaining favorable mechanical properties the present invention also relates to the propellants formulated using the bonding agents described above importantly.
