    • 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.
    • 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结合的线性聚苯硫醚树脂。 组合物还可以含有玻璃纤维,聚四氟乙烯聚合物,聚苯醚聚合物,硅烷偶联剂和/或抗冲改性剂等增强剂。 根据本公开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,同时具有高剪切速率的熔体粘度和在高百分比伸长率下的高工程应力,使得该组合物适于挤出和模塑过程。 根据本公开制备的组合物特别适合于具有复杂形状的模制品。 例如,当生产吹塑成型制品时,组合物可以更好地控制壁厚,同时在较高产量和挤出速率下具有改善的内表面平滑度。
