  Described are aromatic polyesters consisting essentially of 4-oxybenzoyl units, terephthaloyl units, 4,4ʹ-dioxydiphenyl units and 4,4ʹ-dioxydiphenyl ether units which have relatively low transition temperatures to liquid crystals as well as good flow characteristics, and thus have good melt-formability. The polyesters give melt extruded fibers and melt extruded films having superior mechanical strength and elastic moduli, and also give injection-molded products having superior strength, elastic moduli and impact strength.

  所述芳香族聚酯主要由 4-氧苯甲酰基单元、对苯二甲酰基单元、4,4ʹ-二氧二苯基单元和 4,4ʹ-二氧二苯基醚单元组成，这些单元具有相对较低的液晶转变温度和良好的流动特性，因此具有良好的熔融成型性。 这些聚酯可制成具有优异机械强度和弹性模量的熔融挤出纤维和熔融挤出薄膜，还可制成具有优异强度、弹性模量和冲击强度的注塑成型产品。
