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.
