    摘要: Hexabenzylhexaazaisowurtzitane is converted to tetracetyl, dibenzyl azaisowurtzitane. The benzyl groups are removed by catalytic transfer hydrogenolysis leaving a pair of available nitrogens. The available nitrogens are acetylated, and the resulting intermediate is converted to CL-20 with a strong nitrating agent.

    摘要: 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. The poly(&lgr;-laurolactone) is prepared from &lgr;-laurolactone, diethyl zinc and a suitable mono-functional alcohol. Another procedure describes the direct linking of hydroxyl-terminated poly(butadiene) with a poly(&lgr;-laurolactone) with a difunctional isocyanate producing a polymeric material having an (AB)n structure. Also disclosed are chemically uncured high-energy compositions, such as explosives, gasifiers, and especially solid rocket motor propellants, wherein between about 70-91 wt. % of solid particulates, including fuel material and/or oxidizer, and between about 9-30 wt. % of a binder system comprising a thermoplastic, elastomeric block copolymer system as above described and optionally a plasticizer.

    摘要: 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.
