SOLID PROPELLANTS PREPARED FROM ACIDIC VINYLIDENE POLYMERS USING BOTH POLYAZIRIDINYL AND DIFUNCTIONAL AZIRIDINYL CURING AGENTS

摘要

1. A solid propellant composition comprising an inorganic oxidizing salt and a synthetic polymer formed by reacting an uncured polymer of a vinylidene-containing monomer selected from the group consisting of conjugated dienes containing from four to 12 carbon atoms, vinyl-substituted aromatic compounds, vinylpyridines, vinylquinolines, vinylisoquinolines, acrylic acid esters, alkacrylic acid esters, nitriles, N,N-disubstituted amides, vinylfuran, and N-vinylcarbazole, said uncured polymer containing at least one acid group of an element selected from the group consisting of sulfur, carbon, selenium, silicon, tin, antimony, tellurium, and arsenic per molecule, with a combination curative containing a compound having at least three 1-aziridinyl radicals in which the ring carbons are bonded to radicals containing up to a total of 20 carbon atoms and selected from the group consisting of hydrogen, alkyl, cycloalkyl, aryl, alkaryl and aralkyl radicals and a diaziridinyl compound having the formula WHEREIN N IS AN INTEGER OF 1 TO 2 AND EACH R is selected from the group consisting of hydrogen and alkyl radicals containing from one to four carbon atoms.
