Abstract: Disclosed is a UV stabilized polyarylene sulfide composition, methods of forming the composition, and UV stabilized products that can be formed of the composition. The UV stabilized polyarylene sulfide composition can include a reactively functionalized polyarylene sulfide polymer in conjunction with a UV stabilizer. The reactivity of the polyarylene sulfide polymer is formed during melt processing via reaction of a reactively functionalized disulfide compound with a starting polyarylene sulfide. The reactivity of the polyarylene sulfide can encourage interaction between the polyarylene sulfide polymer and the UV stabilizer, which can improve dispersion of the UV stabilizer throughout the composition and improve miscibility between the polyarylene sulfide polymer and the UV stabilizer. Products can incorporate high concentrations of UV stabilizer and/or can be formed to very small cross sectional dimensions without phase separation between the UV stabilizer and the polyarylene sulfide.

Abstract: Blow molded articles are made from a polymeric composition containing a mixture of polyphenylene sulfide resins. For instance, the polymeric composition may contain a linear polyphenylene sulfide resin combined with a branched polyphenylene sulfide resin. The composition can further contain a reinforcing agent, such as glass fibers, a polytetrafluoroethylene polymer, a polyphenylene oxide polymer, a silane coupling agent, and/or an impact modifier. Compositions made according to the present disclosure can have relatively high near zero shear rate melt strengths while also having high shear rate melt viscosities and high engineering stresses at a high percent elongations, making the compositions amenable to extrusion and molding processes. Compositions made according to the present disclosure are particularly well suited to molding articles with a complex shape. When producing blow molded articles, for instance, the composition provides better control over wall thickness while having improved interior surface smoothness at higher throughput and extrusion rates.
Abstract translation: 吹塑制品由含有聚苯硫醚树脂混合物的聚合物组合物制成。 例如，聚合物组合物可以含有与支化聚苯硫醚树脂组合的线性聚苯硫醚树脂。 该组合物可以进一步含有增强剂，例如玻璃纤维，聚四氟乙烯聚合物，聚苯醚聚合物，硅烷偶联剂和/或冲击改性剂。 根据本发明制备的组合物可以具有相对高的接近零剪切速率的熔体强度，同时还具有高剪切速率熔体粘度和高百分比伸长率下的高工程应力，使得组合物适合于挤出和模塑工艺。 根据本公开制造的组合物特别适合模制具有复杂形状的制品。 例如，当生产吹塑制品时，该组合物提供了更好的壁厚控制，同时在更高的生产量和挤出速率下具有改善的内表面光滑度。

Abstract: An injection molded housing for a portable electronic device is provided. The housing contains a thermoplastic composition that includes a polyarylene sulfide melt processed in the presence of a disulfide compound and a filler. Without intending to be limited by theory, it is believed that the disulfide can undergo a chain scission reaction with the starting polyarylene sulfide to lower its melt viscosity, which can lead to decreased attrition of the filler and thus improved mechanical properties. Due to this ability to reduce viscosity during melt processing, the present inventors have discovered that relatively high molecular weight polyarylene sulfides can be fed to the extruder with little difficulty.
Abstract translation: 提供了一种用于便携式电子设备的注塑外壳。 壳体包含热塑性组合物，其包含在二硫化物化合物和填料的存在下加工的聚芳硫醚熔体。 不期望受理论的限制，相信二硫化物可以与起始聚芳硫醚发生断链反应以降低其熔体粘度，这可导致填料的磨损减少，从而改善机械性能。 由于这种在熔融加工过程中降低粘度的能力，本发明人已经发现，相对高分子量的聚亚芳基硫化物可以很少地进料到挤出机中。
