Abstract
HMX-containing gun propellants having good thermal stability and mechanical properties are made by mixing HMX with a polymerizable binder, a polyacrylate cross-linking agent and a polymerization catalyst and extruding the mixture into hot water to form cured pellets of propellant. The binder comprises a long chain acrylic monomer of 14 to 24 carbon atoms or a blend of such a long chain monomer and a shorter chain monomer having 6 to 13 carbon atoms. The molar ratio of short chain acrylic monomer to long chain monomer may vary from 0:1 to 3:1.
