    摘要: Blends of poly(arylene sulfide)s, liquid crystalline polyesters and liquid crystalline poly(esteramide)s exhibit a lower melt viscosity than would be expected based on the melt viscosities of analogous blends of liquid crystalline polyesters and poly(arylene sulfide)s that have the same overall amount of liquid crystalline polymer. The viscosities are reduced over a wide range of compositions. Such blends are useful in the manufacture of electronic components, particularly connectors.

    摘要: Blow molded articles are made from a polymeric composition containing a polyphenylene sulfide resin. The composition can further contain a reinforcing agent, such as glass fibers, and a combination of an organosilane coupling agent and an impact modifier. It was discovered that the combination of the aminosilane coupling agent and the impact modifier substantially increased the low shear viscosity and melt strength of the composition without increasing the high shear viscosity of the composition. The increase in the low shear viscosity makes the composition 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.
