Abstract
Propellants have high energy particulates dispersed in a binder system based upon thermoplastic elastomeric ionomers. In addition to the ionomer, the binder system has an ionolyzer which melts at processing temperatures and facilitates relative movement of ionic segments of the ionomer, plus a plasticizer for hydrophobic, amorphous segments of the ionomer.
