摘要: An improved process for forming polyarylene sulfide fibers is provided. The process comprises forming at least one fiber from a polymer melt comprising a polyarylene sulfide and at least one tin additive comprising a branched tin(II) carboxylate. Using such a melt, the fiber forming continuity is improved compared to that of the native polyarylene sulfide melt processed under the same conditions.

摘要: A method for stabilizing a polymeric structure against thermo-oxidative degradation is described. A polymeric core structure is provided with a skin layer that contains a skin resin in which the skin resin at least partially envelops a portion of the core structure. The skin structure then provides a barrier that thereby stabilizes the portion of the structure that is enveloped. The skin resin is made from a treated polyarylene sulfide.

摘要: A nonwoven web comprising bicomponent fibers. The fibers have continuous phases each of a first polyarylene sulfide (PAS) component and a polymer component. The polymer component may also be a second polyarylene sulfide. The first polyarylene sulfide component contains a tin or a zinc additive or both, and the first polyarylene sulfide component of any given fiber is at least partially exposed to the external surface of that fiber.

摘要: A method for accelerating the curing of a polyarylene sulfide. The polyarylene sulfide is blended with a cure accelerator to form a mixture where the weight percentage of accelerator is between 0.2% and 15.0% of the total weight of the blend. The mixture is cured at 320° C. or above for at least 20 minutes. The cure accelerator is a compound selected from the group consisting of ionomers, hindered phenols, polyhydric alcohols, polycarboxylates, and mixtures of the foregoing.
摘要翻译: 一种加速聚芳硫醚固化的方法。 将聚芳硫醚与固化促进剂混合以形成混合物,其中促进剂的重量百分数在共混物的总重量的0.2%至15.0%之间。 混合物在320℃以上固化至少20分钟。 固化促进剂是选自离聚物,受阻酚,多元醇,多羧酸盐以及前述物质的混合物的化合物。
