Abstract : The present invention relates to a method for preparing a solid rocket motor propellant grain restrictor which prevents chamber pressure buildup (spiking) and erosive burning upon ignition. This restrictor can be used on any hydroxyl-terminated polybutadiene (HTPB) propellant grain and on various polyurethane propellant grains which employ an isocyanate cure.
