摘要： A biodegradable polyester composition based on a total weight of the biodegradable polyester composition, including a weight content of tetrahydrofuran, which is 3 ppm-200 ppm; and based on the total weight of the biodegradable polyester composition, a weight content of cyclopentanone is 0.5 ppm-85 ppm is provided. The tetrahydrofuran and cyclopentanone is added into the composition and controlling the content of tetrahydrofuran and the content of cyclopentanone in a certain range in the composition to realize printing performance. Moreover, when a velocity of film blowing is 176 Kg/h, a range of a film thickness is less than 0.2 μm and a relative deviation of the film thickness is less than 1%.

摘要： A biodegradable polyester composition based on a total weight of the biodegradable polyester composition, including a weight content of a cyclic ester compound having a structure shown as formula (I), which is 100 ppm-950 ppm; and based on the total weight of the biodegradable polyester composition, a weight content of cyclopentanone is 0.5 ppm-85 ppm is provided. The cyclic ester compound and cyclopentanone is added into the composition and controlling the content of the cyclic ester compound and the content of cyclopentanone in a certain range in the composition to realize an anti-thermal oxidative aging property of the biodegradable polyester composition. In addition, a film is prepared by blow molding or a part is prepared by injection molding after being digested with 95% ethanol at 40° C. for 240 hours.

摘要： The present invention discloses a PBAT resin composition comprising: (a) Poly (butyleneadipate-co-terephthalate); (b) a cyclic esterified product having a structure represented by the formula (I) Wherein the content by weight of the cyclic esterified product is from 10 ppm to 2000 ppm, based on the total weight of the PBAT resin composition. In the present invention, the service life of the PBAT resin composition can be greatly extended by adding cyclic esterified product in the PBAT resin composition and controlling the content of the cyclic esterified product in the composition in the range of 10 ppm to 2000 ppm. And after boiled for 240 hours in 95% ethanol at 40° C., the film produced from blowing or the articles produced from injection have less surface precipitates, with excellent surface appearance properties.
