摘要： The present invention discloses a PBAT resin composition comprising following components: (a) poly(butyleneadipate-co-terephthalate); (b) iron element; wherein, based on a total weight of the PBAT resin composition, a weight content of the iron element is 1ppm-500ppm. By adding iron-containing compounds into the composition and controlling the content of the iron element in a range of 1ppm-500ppm in the composition, a speed of reaction of aromatic structure in the PBAT resin under a hot and humid condition can be postponed, so that after the prepared PBAT resin composition is aged in boiling water for 24 hours and 48 hours, a variation of b-value is less than 2. The PBAT resin composition has obviously improved color stability in resistance to boiling water aging.
摘要翻译： 本发明公开了一种PBAT树脂组合物，其包含以下组分：（a）聚（亚丁基己二酸酯 - 共 - 对苯二甲酸酯）; （b）铁元素; 其中，基于PBAT树脂组合物的总重量，铁元素的重量含量为1ppm-500ppm。 通过向组合物中添加含铁化合物，并且在组合物中将铁元素的含量控制在1ppm〜500ppm的范围内，可以推迟PBAT树脂在炎热和潮湿条件下的芳香族结构的反应速度，所以 在制备的PBAT树脂组合物在沸水中老化24小时和48小时后，b值的变化小于2.PBAT树脂组合物具有明显改进的耐沸水老化的颜色稳定性。

摘要： The present invention discloses a poly(terephthalate-co-sebacate) resin composition, comprising the following components: a. poly(terephthalate-co-sebacate); and b. an alkane, which is at least one selected from the group consisting of hexadecane, heptadecane, octadecane, nonadecane and eicosane; wherein a weight content of the alkane is 5ppm-1000ppm based on a total weight of the poly(terephthalate-co-sebacate) resin composition. The present invention controls the content of alkane in the composition within a range of 5ppm-1000ppm by adding an alkane, which not only enables the poly(terephthalate-co-sebacate) resin to have obviously improved blow molding properties, a film thickness range of less than 0.3 µm, and a relative deviation of film thickness of less than 2.0%, thereby guaranteeing a bubble stability and a continuity of blow molding, but also enables the film material to prevent the ink from stripping off the film material, and to prevent excessive ink from adhering to the film material in the printing process, so that the film shows excellent printing performance.
