    Abstract: Glycerol is nitrated with at least one nitrating source in a solvent to form a nitrated glycerol solution containing dinitroglycerin. The nitrated glycerol solution is treated with at least one cyclizing agent to convert the dinitroglycerin into glycidyl nitrate, which is polymerized into poly(glycidyl nitrate) (PGN). Distillation or other vaporization techniques are not required to remove nitroglycerin from the glycidyl nitrate prior to polymerization of the glycidyl nitrate. Rather, the nitroglycerin can be carried along with the dinitroglycerin during polymerization. As a consequence, the glycidyl nitrate is not exposed to elevated temperatures sufficient to cause accidental explosion or deflagration of the nitrate ester. Still more preferably, the glycidyl nitrate is not heated above room temperature at any time prior to polymerization. Moreover, given the high energy performance of nitroglycerin, the nitroglycerin can optionally be retained with the PGN, i.e.

  • Patent number: 6103029
    Abstract: Polyethers containing pendant azide groups are cured without a catalyst by yclo-addition with diacetylenes to form triazole cross-linked, energetic binders having improved mechanical properties and stability. The polyethers typically have three hydroxy-terminated chains each of about 5000 to about 50,000 daltons. Ideally, only one azide group per chain reacts by cyclo-addition since the diacetylene is added in a proportion of about one molecule to each two polyether chains. Repeating units of glycidal azide, azidomethylmethyloxetane, bis-azidomethyloxetane/nitratomethylmethyloxetane, and bis-azidomethyloxetane/azidomethylmethyloxetane are believed effective as polyethers when used with the diethynlbenzenes 1,4-bis(ethynl)benzene, 1,4-bis(ethynlcarbonyl)benzene, and 1,3-bis(cyanoethynl)benzene. The polyethers may be further cross-liked at the hydroxyl terminations by urethane bonds.

  • Patent number: 5760142
    Abstract: Epoxide-amine dendrimers synthesized by a repetitive and step-wise addition reaction of epoxides comprising functional moieties which are available for conversion into amino groups followed by a reaction of these groups to primary amino moieties. The amino terminated dendrimers are reacted with (2,3-epoxypropoxy) methacrylate, a monoepoxide and/or a monoisocyante. The methacrylate terminated dendrimers are polymerizable using redox initiators and/or photoinitiators. The resulting dendrimers show a very low volume shrinkage from that of the starting materials, on the order of less than about 5 percent by volume.

  • Patent number: 5405938
    Abstract: The present invention describes a polymer composition effective to bind, in a sequence-specific manner to a target sequence of a duplex polynucleotide, at least two different-oriented Watson/Crick base-pairs at selected positions in the target sequence. The composition includes an uncharged backbone with 5- or 6-membered cyclic backbone structures and selected bases attached to the backbone structures effective to hydrogen bond specifically with different oriented base-pairs in the target sequence. Also disclosed are subunits useful for the construction of the polymer composition. The present invention further includes methods for (i) coupling a first free or polymer-terminal subunit, and (ii) isolating, from a liquid sample, a target duplex nucleic acid fragment having a selected sequence of base-pairs.

  • Patent number: 5313000
    Abstract: This invention relates to the production of hydroxy-terminated polymers in the 2,000-20,000 MW range suitable for use as prepolymers in curing reactions with isocyanates to produce elastomers. The process involves the continuous addition over periods of 25-50 hours of an oxirane (monoepoxide) or a mixture of an oxirane and an oxetane to a reaction mixture, consisting of stoichiometric excesses of oxonium ion-forming catalyst such as BF.sub.3 -etherate and a diol initiator dissolved in an inert solvent. Under these conditions, chain extension of the diol occurs and the formation of cyclic oligomers and other impurities is minimised. The mole ratio of the initiator to catalyst is maintained at above 10:1 to suppress the formation of cationic terminal species on the growing polymer chain.
