摘要： THIS PATENT DESCRIBES A NOVEL STORABLE EPOXY-IMIDE RESIN PRECURSOR COMPRISING A CURABLE OXIRANE MONOMER AND AN IMIDE, THE IMPROVEMENT WHEREIN THE SYSTEM IS PROVIDED WITH AN ACTIVATED CHROMIUM III TRICARBOXYLATE SALT CATALYST WHICH CONTAINS AVAILABLE COORDIATION SITES, AND WHICH SITES ARE RENDERED UNAVAILABLE IN THE PRESENCE OF CERTAIN NON-REACTIVE, REMOVABLE ELECTRON DONATING SOLVENTS. THAT IS TO SAY, THE CATALYST COMPOUND, IN THE PRESENCE OF PARTICULAR SOLVENTS IS RENDERED NONCATALYTIC; ON THE REMOVAL OF SAID SOLVENTS, CATALYTIC ACTIVITY IS RESTORED. THESE SOLVENTS INCLUDE BUT ARE NOT LIMITED TO SUCH POLAR ELECTRON COORDINATING SOLVENTS AS REMOVABLE METHANOL, ETHANOL, N,N-DIMETHYL FORMAMIDE, DIOXANE, TETRAHYDROFURAN, DIMETHYL SULFOXIDE, DIMETHYL SULFOLANE, NITRO ALKANES, NITRO AROMATICS, TETRAMETHYL UREA, N,N-DIMETHYLACETAMIDE, N-METHYLCAPROLACTAM AND N-METHYL PYRROLIDONE. UPON THE REMOVAL OF ONLY THE SOLVENT AS BE EVAPORATION, THE ACTIVITY OF THE CATALYST IS RESTORED, BY THE FORMATION OF UNOCCUPIED COORDINATION SITES, WHEREBY THE REACTION OF THE OXIRANE COMPOUND WITH THE IMIDE CAN TAKE PLACE.

摘要： THIS INVENTION RELATES TO A METHOD OF MODIFYING SOLID COMPOSITE PROPELLANT COMBUSTION OR PROCESSING PROPERTIES OR BOTH WHEREBY ALL OR PART OF THE SOLID FILLER IS CONCENTRATED IN A FILLER-RICH POWDER OF CONTROLLED PARTICLE SIZE AND SHAPE WHICH IS THEN DISPERSED IN A BINDER-RICH MATRIX TO FORM A COMPOSITE SOLID PROPELLANT. THIS INVENTION INCLUDES, BUT IS NOT LIMITED TO, A METHOD OF FORMING THE FILLER-RICH POWDER WHICH COMPRISES LOADING A HIGH PERCENTAGE OF SMALL PARTICLE-SIZE SOLID FILLERS IN A SUITABLE BINDER, FORMING A CAKE, AND SUBSEQUENTLY GRINDING OF THE CAKE IN CONVENTIONAL EQIUPMENT TO YIELD A POWDER OF ANY DESIRED PARTICLE SIZE DISTRIBUTION. THE POWDER THUS OBTAINED IS THEN FORMULATED INTO A SOLID PROPELLANT BY THE USE OF ADDITIONAL BINDERS AND USUALLY, BUT NOT NECESSARILY, SOME ADDITIONAL FILLER SOLIDS.
