A polymer blend which is capable of exhibiting an anisotropic melt phase, improved processability characteristics and the ability to form molded articles having satisfactory mechanical properties is provided. The polymer blend comprises approximately 5 to approximately 95 percent by weight, based upon the total weight of the blend, of a polyarylene sulfide and approximately 5 to approximately 95 percent by weight, based upon the total weight of the blend, of a melt processable wholly aromatic polyester which is capable of forming an anisotropic melt phase apart from the blend. Blend compositions containing high concentrations of wholly aromatic polyester (i.e., at least 60 percent by weight wholly aromatic polyester) can be used to form fibers and films.
本发明提供了一种聚合物混合物,该混合物能够显示出各向异性熔融相、改进的加工特性以及形成具有令人满意的机械特性的模塑制品的能力。该聚合物混合物包括按混合物总重量计算的约 5%至约 95%(重量百分比)的聚芳基硫醚和按混合物总重量计算的约 5%至约 95%(重量百分比)的可熔融加工的全芳香族聚酯,该聚酯能够在混合物之外形成各向异性熔融相。含有高浓度全芳香族聚酯(即至少 60% 的全芳香族聚酯重量比)的混合物组合物可用来形成纤维和薄膜。
