  Polyester polymers consisting essentially of repeating units having the formula repeating units having the formula repeating units having the formula and repeating units having the formula wherein Ar1 is selected from Ar2 is selected from halogen substituted radicals of these radicals, and wherein X is selected from -0-, -S-, -SOr, -CO-, wherein each n independently represents a member having a value of from 1 to 10, and each R4 is independently selected from alkyl radicals of 1 to 5 carbon atoms, and R2 and R3 are independently selected from hydrogen atom, halogen radicals, alkyl radicals of 1 to 5 carbon atoms, and phenyl radical, and R2 and R3 may be identical or different from. each other, and R1 is selected from halogen radicals and alkyl radicals of 1 to 5 carbon atoms, and wherein the polyester polymer has a reduced viscosity [ sp/c] of at least 0.2 dl/g as measured in p-chlorophenol at a concentration of 0.2 g/dl at 60 °C . Such polyester polymers are excellent in the mechanical strength and heat resistance and, therefore, are useful as various kinds of fibers, films, or engineering plastics. A process for preparing the polyester polymer and novel diimide-dicarboxylic acid to be used as a material in this process are also disclosed.

  主要由以下式子的重复单元组成的聚酯聚合物 式的重复单元 式的重复单元 和具有以下式子的重复单元 其中 Ar1 选自 Ar2 选自 这些基的卤素取代基，以及 其中 X 选自-0-、-S-、-SOr、-CO-、 其中每个 n 独立地代表数值为 1 至 10 的成员，每个 R4 独立地选自 1 至 5 个碳原子的烷基，以及 R2 和 R3 独立地选自氢原子、卤素基、1 至 5 个碳原子的烷基和苯基，且 R2 和 R3 可以相同或不同，以及 R1 选自卤素基和 1 至 5 个碳原子的烷基，其中聚酯聚合物的还原粘度[ sp/c] 至少为 0.2 dl/g，该粘度是在对氯苯酚浓度为 0.2 g/dl 时于 60 °C 测得的。 这种聚酯聚合物具有优异的机械强度和耐热性，因此可用作各种纤维、薄膜或工程塑料。此外，还公开了制备聚酯聚合物的工艺和在该工艺中用作材料的新型二亚胺二羧酸。
