  A polyester polymerization catalyst consisting mainly of components except for antimony compounds or germanium compounds which exhibits an excellent catalyst activity and yields a highly thermally stable polyester whose thermal degradation upon a melt process is suppressed efficiently without any need of an inactivation or a removal of the catalyst, a polyester obtained using said polyester polymerization catalyst, and a method for producing a polyester using said polyester polymerization catalyst are provided. A polyester polymerization catalyst is one which contains no antimony or germanium, whose activity parameter (AP) fulfills the relationship: AP(min)<2T (min), which gives, when used in a polymerization, a thermal stability degree (TD) of a resultant polyethylene terephthalate fulfilling the requirement: TD (%)<25, and which comprises a metal-containing component and an organic compound component having an Ar-O- and/or an Ar-N< unit. A polyester can be used in various molded articles such as a fiber, a film, a sheet and a hollow article.

  本发明提供了一种主要由锑化合物或锗化合物以外的组分组成的聚酯聚合催化剂，该催化剂具有优异的催化剂活性，并能产生热稳定性极高的聚酯，其在熔融过程中的热降解被有效地抑制，而无需对催化剂进行失活或移除处理；还提供了一种使用所述聚酯聚合催化剂获得的聚酯，以及一种使用所述聚酯聚合催化剂生产聚酯的方法。聚酯聚合催化剂是不含锑或锗的催化剂，其活性参数（AP）符合以下关系：AP(min)<2T(min)，当用于聚合时，生成的聚对苯二甲酸乙二酯的热稳定性度(TD)符合要求：TD(%)<25，它由含金属成分和具有 Ar-O- 和/或 Ar-N< 单元的有机化合物成分组成。聚酯可用于各种成型制品，如纤维、薄膜、片材和中空制品。

  The present invention provides processes for producing polyester. In one of the embodiments, the invention provides a process for producing polyester, comprising adding a catalyst in a polycondensation reaction, esterification reaction or transesterification reaction between components comprising at least a polyfunctional alcohol and at least a polyfunctional carboxylic acid or ester-forming derivative of a polyfunctional carboxylic acid to produce the polyester; and obtaining the polyester, wherein the polymerization catalyst comprises an aluminum substance and a phosphorus compound, wherein the aluminum substance is selected from the group consisting of aluminum hydroxide and aluminum alkoxides, and wherein the phosphorus compound has an aromatic ring structure.
