  • Patent number: 9617387
    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.

  • Publication number: 20110257363
    Abstract: The present invention relates to a method for preparing polyarylene sulfide, in which the polyarylene sulfide is prepared by a polymerization reaction of reactants including a diiodo aromatic compound and a sulfur compound, the method including: further adding 0.01 to 10.0 wt. % of diphenyl disulfide with respect to the weight of the polyarylene sulfide to the reactants to form the polyarylene sulfide having a melting point of 265 to 320° C. The diphenyl disulfide included in the reactants according to the present invention costs far less than other conventional polymerization inhibitors to dramatically lower the production cost, and the polyarylene sulfide prepared using the diphenyl disulfide exhibits low iodine content and very excellence in thermal stability.

  • Publication number: 20110218298
    Abstract: High molecular weight disulfide polymers are synthesized in aqueous media by exposing dithiol compounds to a mild oxidizing environment in the presence of a tertiary amine catalyst. The unique oxidizing system polymerizes monomers through the formation of sulfur-sulfur bonds between dithiol compounds. The same oxidizing system may be used to make disulfide-crosslinked gels from compounds containing multiple thiol groups. The oxidizing system is comprised of oxygen at atmospheric concentration and dilute hydrogen peroxide. A filler such as carbon black may be incorporated into the polymer or cross-linked gel during polymerization. A polydisulfide polymer is provided having a weight average molecular weight of greater than about 100,000 g/mol and a polydispersity index of about 2 or less. A tetrathiol composition results from a reaction of a diacrylate with a trithiol.
