Patent number: 9199886Abstract: Gas-generating compositions and methods for their use are provided. Metal complexes are used as gas-generating compositions. These complexes are comprised of a metal cation template, a neutral ligand containing hydrogen and nitrogen, and sufficient oxidizing anion to balance the charge of the complex. The complexes are formulated such that when the complex combusts, nitrogen gas and water vapor is produced. Specific examples of such complexes include metal nitrite amine, metal nitrate amine, and metal perchlorate amine complexes, as well as hydrazine complexes. A binder and co-oxidizer can be combined with the metal complexes to improve crush strength of the gas-generating compositions and to permit efficient combustion of the binder.

Patent number: 6350330Abstract: A thermoplastic, elastomeric block copolymer comprises at least one poly(butadiene) and at least one pair of poly(lactone) blocks flanking the poly(butadiene) block. Each poly(lactone) block is derived from a lactone having between 8 and 18 carbon atoms in the lactone ring, such as &lgr;-laurolactone and 10-hydroxyl decanoic acid lactone. Alternative methods of making these block polymers are also disclosed. In the first procedure diethyl zinc reacts with the hydroxyl end group of a butadiene polymer to form an intermediate zinc alkoxide-tipped polybutadiene which functions as the active initiating species. The laurolactone polymer then grows off the hydroxyl end groups of the butadiene to form the desired ABA block copolymer. In another related procedure for making ABA block polymers, previously prepared difunctional hydroxyl-terminated polybutadiene blocks are linked with monofunctional poly(&lgr;-laurolactone) blocks using a diisocyanate and a catalyst.Type: GrantFiled: November 21, 1990Date of Patent: February 26, 2002Assignee: Alliant Techsystems Inc.Inventors: Robert B.

Patent number: 6107483Abstract: A process for synthesizing 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo-[5.5.0.0.sup.5,9 0.sup.3,11 ]-dodecane ("TEX") involves combining at least one hexa-substituted piperazine derivative with a medium containing at least one nitronium anion source and at least one acid sufficiently strong to generate nitronium anions from the nitronium anion source. According to this invention, TEX yield is significantly improved by pre-heating the medium to 55.degree. C. to about 70.degree. C. and maintaining the medium from 55.degree. C. to about 70.degree. C. to permit the hexa-substituted piperazine derivative and nitronium anions to react and form the TEX. At least one NO.sub.x scavenger is added to the medium, preferably before the addition of the hexa-substituted piperazine derivative, to increase TEX yield.Type: GrantFiled: July 28, 1999Date of Patent: August 22, 2000Assignee: Cordant Technologies Inc.Inventors: Robert B.
