摘要： Disclosed are a biodegradable polyester and the use thereof, said biodegradable polyester comprising: A) an acid component comprising the following repeating units: 40-48 mol% of terephthalic acid A1; 38.5-50 mol% of sebacic acid A2; and 2-20 mol% of aliphatic dibasic acid A3 having a carbon chain length with less than or equal to 6 carbons; and B) a butanediol. With a low content of terephthalic acid, the introduction of the aliphatic dibasic acid monomer having a carbon chain length with less than or equal to 6 carbons sensibly improves the mechanical property of the material, specifically, when storing the material in a humid environment so as to maintain the good mechanical property retention rate.

摘要： The present invention discloses a PBS resin composition and a preparation method thereof. The PBS resin composition comprises the following components: a. PBS resin; b. element titanium; c. element phosphorus, wherein a range of a weight ratio of the element titanium to the element phosphorus is 0.6-10:1, preferably 0.7-4:1, and more preferably 1.25-1.5:1. A weight content of the element titanium is 20-200 ppm, and a weight content of the element phosphorus is 15-70 ppm. By adding a titanium-containing compound and a phosphorus-containing compound and controlling the range of the weight ratio of the element titanium to the element phosphorus in the PBS resin composition to be 0.6-10:1, the present invention obtains a PBS resin composition. After treating in a 95°C-distilled water bath for 12 hours and drying at 90°C for 3 hours, a change of the melt flow index of the PBS resin composition is less than 50.0 g/lOmin, and the PBS resin composition possesses an obviously improved hydrolysis property.

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.
