  A process for producing a polymer blend which exhibits an anisotropic melt phase and is capable of forming shaped articles having satisfactory mechanical properties is provided. The process comprises the steps of (a) post-polymerizing a melt processable wholly aromatic polyester which is capable of forming an anisotropic melt phase apart from the blend and (b) subsequently intimately mixing together approximately 85 to 95 percent by weight of the wholly aromatic polyester and approximately 5 to 15 percent by weight of a polyalkylene terephthalate. The post-polymerizing step is conducted at a temperature and for a period of time sufficient to increase the inherent viscosity of the wholly aromatic polyester by at least approximately 50 percent, preferably by at least approximately 100 percent. The polyalkylene terephthalate is preferably polyethylene terephthalate. The present invention further provides a polymer blend which is capable of exhibiting an anisotropic melt phase and the ability to form shaped articles having satisfactory mechanical properties. The blend comprises (a) approximately 5 to 16 percent by weight of a polyalkylene terephthalate and (b) approximately 85 to 95 percent by weight of a melt processable wholly aromatic polyester which is capable of forming an anisotropic melt phase apart from the blend, the wholly aromatic polyester having been subjected prior to blending to post-polymerization so as to increase the inherent viscosity thereof by at least approximately 50 percent. The blend preferably comprises approximately 10 percent by weight of the polyalkylene terephthalate and approximately 90 percent by weight of the melt processable wholly aromatic polyester.

  本发明提供了一种生产聚合物共混物的工艺，该共混物具有各向异性的熔体相，并能形成具有令人满意的机械性能的成型物品。该工艺包括以下步骤：(a) 对可熔融加工的全芳香族聚酯进行后聚合，该聚酯可与混合物分开形成各向异性熔融相；(b) 随后将约 85% 至 95% （按重量计）的全芳香族聚酯和约 5% 至 15% （按重量计）的聚对苯二甲酸乙二醇酯紧密混合在一起。后聚合步骤的温度和时间足以将全芳香族聚酯的固有粘度提高至少约 50%，最好是至少约 100%。聚对苯二甲酸乙二醇酯最好是聚对苯二甲酸乙二醇酯。 本发明进一步提供了一种聚合物混合物，它能够表现出各向异性的熔融相，并能形成具有令人满意的机械性能的成型物品。该共混物包括：(a) 大约 5%至 16%（按重量计）的聚对苯二甲酸乙二醇酯；(b) 大约 85%至 95%（按重量计）的可熔融加工的全芳香族聚酯，该聚酯能够在共混物之外形成各向异性熔融相，全芳香族聚酯在共混之前已进行后聚合，使其固有粘度至少增加大约 50%。混合物最好包括约 10%（按重量计）的聚对苯二甲酸乙二醇酯和约 90%（按重量计）的可熔融加工的全芳香族聚酯。
