Abstract 2. A solid propellant composition comprising a cured intimate mixture of a solid inorganic oxidizing salt, said inorganic oxidizing salt being present in an amount of from about 45 percent to about 90 percent by weight of the total propellant composition; an unsaturated polyester resin consisting of the condensation product of a saturated polyhydric alcohol and polycarboxylic acid, said polyester resin being the condensation product of an alkylene glycol, maleic anhydride and sebacic acid heteropolymerized with an unsaturated compound selected from the group consisting of lower alkenes, lower alkynes, phenyl substituted lower alkenes, lower alkyl dienes, lower alkenyl esters of lower alkanoic acids, lower alkyl esters of lower alkanoic acids, lower alkenyl esters of lower alkanoic acids, allyl diglycol carbonate, diallyl diglycollate, and mixtures thereof; and a burning rate catalyst comprising an inorganic oxide selected from the group consisting of the oxides of vanadium, cobalt, iron, chromium, manganese, copper, silver, and mixtures thereof.
A SOLID PROPELLANT COMPOSITION COMPRISING A CURED INTIMATE MIXTURE OF A SOLID INORGANIC OXIDIZING SALT, SAID INORGANIC OXIDIZING SALT BEING PRESENT IN AN AMOUNT OF FROM ABOUT 45 PERCENT TO ABOUT 90 PERCENT BY WEIGHT OF THE TOTAL PROPELLANT COMPOSITION; AN UNSATURATED POLYESTER RESIN CONSISTING OF THE CONDENSATION PRODUCT OF A SATURATED POLYHYDRIC ALCOHOL AND POLYCARBOXYLIC ACID, SAID POLYESTER RESIN BEING THE CONDENSATION PRODCUT OF AN ALKYLENE GLYCOL, MALEIC ANHYDRIDE AND SEBACIC ACID HETEROPOLYMERIZED WITH AN UNSATURATED COMPOUND SELECTED FROM THE GROUP CONSISTING OF LOWER ALKENES, LOWER ALKYNES, PHENYL SUBSTITUTED LOWER ALKENES, LOWER ALKYL DIENES, LOWER ALKENYL ESTERS OF LOWER ALKANOIC AICDS, LOWER ALKYL ESTERS OF LOWER ALKANOIC ACIDS, LOWER ALKENYL ESTERS OF LOWER ALKANOIC ACIDS, ALLYL DIGLYCOL CARBONATE, DIALLYL DIGLYCOLLATE, AND MIXTURES THEREOF; AND A BURING RATE CATALYST COMPRISING AN INORGANIC OXIDE SELECTED FROM THE GROUP CONSISTING OF THE OXIDES OF VANADIUM, COBALT, IRION, CHROMIUM, MANAGANESE, COPPER, SILVER, AND MIXTURES THEREOF.
