    Abstract: A method and system for formation of a polyarylene sulfide is described. The method includes a first stage in which a complex is formed in a reactor. The complex includes the hydrolysis product of an organic amide solvent and an alkali metal hydrosulfide. The complex formation reaction also forms hydrogen sulfide as a by-product. The method also includes treating a fluid stream that is pulled off of the reactor. The treatment includes scrubbing the fluid stream to recover hydrogen sulfide from the stream and return the hydrogen sulfide to the reactor. The recovery and recycle of the hydrogen sulfide can prevent loss of sulfur from a polyarylene sulfide formation process.

  • Patent number: 6218496
    Abstract: Disclosed is a polyimidesiloxane adhesive made by reacting in a solution of an organic solvent a dianhydride selected from the group consisting of biphenyl dianhydride and oxydiphthalic anhydride with an approximately stoichiometric amount of a diamine. The diamine is a mixture of about 5 to about 30 mole % of a siloxane-containing diamine and about 70 to about 95 mole % of a non-siloxane containing diamine. The non-siloxane containing diamine is a mixture of about 10 to about 90 mole % each of at least two of the diamines 2,2-bis(4[4-aminophenoxy]phenyl) propane, &agr;,&agr;′-bis(4-aminophenyl)-1,4-diisopropylbenzene, 3,3′-diaminophenylsulfone, and 1,3-bis(3-aminophenoxy)benzene. The adhesive can be made into one, two, and three-layer tapes (or dispensed in other ways) which have a high Tg and a relatively low bonding temperature.

  • Patent number: 6168782
    Abstract: Elastomeric silicones, especially elastomeric silicone polyethers, are prepared by combining and reacting (A) an ≡Si—H containing polysiloxane, (B) a mono-alkenyl polyether, (C) an active ingredient such as a vitamin, antimicrobial agent, sunburn prevention agent, astringent, or sex hormone, (D) an &agr;,&ohgr;-unsaturated hydrocarbon, (E) a platinum catalyst, and (F) an oil. The reaction of components (A)-(F) is allowed to continue, forming a crosslinked three-dimensional gelled network of the elastomeric silicone polyether containing the active ingredient and the oil. The compositions are useful in personal and health care applications, personal hygiene, and household cleaning applications.

  • Patent number: 5985969
    Abstract: Polyimide precursor solutions comprise an organic liquid and the reaction product of an aromatic dianhydride and an aromatic diaminobenzoxazole capped, on at least one terminal end, with a bifunctional chain extender. The bifunctional chain extender has one functional group reactive with the amine of the aromatic diaminobenzoxazole or the anhydride of the aromatic dianhydride and another functional group which does not form amic acid linkages, but which is capable of further reaction to increase the molecular weight of the polyimide precursor under conditions other than those used to react the aromatic diamine and aromatic dianhydride to form the polyimide precursor. These polyimide precursors can be converted into polyimidebenzoxazole polymers.

  • Patent number: 5889108
    Abstract: Low molecular weight siloxane fluids are thickened by silicone elastomers. The silicone elastomers are made by combining in one pot an .tbd.Si--H containing siloxane, a mono-alkenyl polyether, an alpha, omega-diene, and a low molecular weight siloxane fluid. An elastomer, i.e. gel, with polyether groups is produced. The elastomer can be swollen with the low molecular weight siloxane fluid under shear force, to provide a uniform silicone paste. The silicone paste has excellent spreadability upon rubbing, and possesses unique rheological properties in being thixotropic and shear thinning. The silicone paste can be easily emulsified with water to form a stable uniform emulsion, without using a surfactant to allow normally immiscible materials to become intimately mixed.

  • Patent number: 5886139
    Abstract: To economically produce a polyacetal copolymer excellent in properties including thermal stability by copolymerizing trioxane as the main monomer through simple steps, a polyacetal copolymer is produced by copolymerizing trioxane as the main monomer using a nonvolatile protonic acid catalyst as a polymerization catalyst until the conversion reaches at least 60% (based on all monomers), and then vaporizing unreacted monomers to separate, remove, and recover the same from the polymerization system to thereby reduce the residual monomer content of the polymerization system to 5% by weight or lower.

  • Patent number: 5821299
    Abstract: The present invention relates to a process for separating polyhydroxyalkanoate (PHA) from a biomass comprising the PHA, the process comprising: a) treating the biomass with a PHA solvent and a marginal nonsolvent for PHA; b) removing any insoluble biomass, thereby leaving behind a solution of PHA and marginal nonsolvent for PHA; and c) removing the PHA solvent from the solution, thereby resulting in a suspension of precipitated PHA in the marginal nonsolvent for PHA. Optionally, the process further comprises removing the marginal nonsolvent for PHA, thereby leaving behind the PHA. The present invention further relates to the suspension and the PHA produced by the process.

  • Patent number: 5811506
    Abstract: An extrudable urea-extended thermoplastic polyurethane elastomer is formed from at least one aliphatic diisocyanate, at least one polyester glycol or polyether glycol, and at least one diamine curing agent. At least one second diamine curing agent and/or at least one extrusion processing aid may be included. The polyurethane has high-temperature-resistance and is thus extrudable at high temperatures. The polyurethane is also strong and durable. The polyurethane can be liquid-cast, injection-molded, transfer-molded, sprayed, and extruded without changing either the chemistry or stoichiometry of the polyurethane. The polyurethane may be used for making vehicle air bags or other any application for thermoplastic urethanes which requires increased thermal stability.
