    摘要: 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.
