Melt-processable polyesteramides capable of exhibiting melt-phase anisotropy at temperatures of approximately 360°C and lower are disclosed. The polyesteramides contain certain essential 2,2′-substituted biphenylene radicals and repeating units which provide ester and amide linkages. The polyesteramides exhibit melt processability suitable for processing into films and fibers.
本发明公开了可熔融加工的聚酯酰胺,它们能够在大约 360°C 或更低的温度下表现出熔融相各向异性。这种聚酯酰胺含有某些必需的 2,2′-取代
联苯基和提供酯和酰胺连接的重复单元。聚酯酰胺具有适合加工成薄膜和纤维的熔融加工性。
