摘要： The present invention discloses a biodegradable polyester and use thereof, including components:
A) containing repeating units of acid components as follows:
50 to 58 mol% of terephthalic acid A1;
30 to 40 mol% of sebacic acid A2; and
2 to 20 mol% of an aliphatic dibasic acid A3 with a carbon chain length of 6 or less;

摘要： The present invention discloses a biodegradable polyester composition, wherein based on a total weight of the biodegradable polyester composition, a weight content of a cyclic ester compound having a structure shown as formula (I) is 100ppm-950ppm;
and based on the total weight of the biodegradable polyester composition, a weight content of cyclopentanone is 0.5ppm-85ppm. In the present invention, by adding the cyclic ester compound and cyclopentanone into the composition and controlling the content of the cyclic ester compound and the content of cyclopentanone in a certain range in the composition, an anti-thermal oxidative aging property of the biodegradable polyester composition can be greatly improved. Besides, after being digested with 95% ethanol at 40°C for 240 hours, a film prepared by blow molding or a part prepared by injection molding has little precipitate separating out of the surface and has an excellent surface appearance property. In addition, the lubrication degree of film during the blow molding process of the biodegradable polyester can be improved. When the velocity of film blowing is 176 Kg/h, a range of a film thickness is less than 0.2µm and a relative deviation of the film thickness is less than 1%. Bubble stability and continuity of film blowing are guaranteed.摘要翻译： 本发明公开了一种生物可降解聚酯组合物，其中基于生物可降解聚酯组合物的总重量，具有式（I）所示结构的环状酯化合物的重量含量为100ppm-950ppm; 基于生物可降解聚酯组合物的总重量，环戊酮的重量含量为0.5ppm-85ppm。 在本发明中，通过将环状酯化合物和环戊酮添加到组合物中，并且在组合物中控制环酯化合物的含量和环戊酮的含量在一定范围内，可生物降解的聚酯组合物的抗热氧化老化性能 可以大大提高。 此外，用95％乙醇在40℃下消化240小时后，通过吹塑或通过注塑制备的部件制备的膜具有很少的从表面析出的沉淀，并具有优异的表面外观性能。 另外，可生物降解聚酯的吹塑成型过程中膜的润滑度可以得到改善。 当吹膜速度为176Kg / h时，膜厚范围小于0.2μm，膜厚相对偏差小于1％。 泡沫稳定性和吹膜连续性得到保证。
