Description

本発明は、繊維、フィルム及びシート、樹脂成形品、食品包装容器（ボトル、容器等）、非食品容器（医薬品、ドリンク剤等）に好適に使用することができるように、ポリエステル本来の特性を全く損なわず、生産性を向上させつつ、かつ、ポリエステルの色相悪化を抑制することを可能とする。また、上記の用途に用いる際重要な品質である、ガスバリア性、染色性、色相等に大きく影響するジエチレングリコールの副生成量を抑制することを可能とする。



The present invention has the inherent characteristics of polyester so that it can be suitably used for fibers, films and sheets, resin molded products, food packaging containers (bottles, containers, etc.), and non-food containers (pharmaceuticals, drinks, etc.). It is possible to improve the productivity and suppress the deterioration of the hue of the polyester without any loss. In addition, it is possible to suppress a by-product amount of diethylene glycol that greatly affects gas barrier properties, dyeability, hue, and the like, which are important qualities when used in the above applications .
