摘　　要：对枝状PBS基脂肪族聚酯的合成工艺进行研究,采用控制变量法,分别单一改变变量:催化剂,酯化时间,缩聚时间,酯化温度,缩聚温度,通过生成物的颜色以及出水量的数据,找到合成枝状PBS的最佳工艺条件:将丁二酸、丁二醇、丙二醇、双催化剂(对甲苯磺酸和氯化亚锡)和50 m L甲苯加入三口烧瓶中。使用双催化剂,酯化温度130℃,酯化时间为1.0 h,缩聚温度在220℃,缩聚时间为3.0 h,为进一步研究PBS基脂肪族共聚酯奠定基础。PBS based aliphatic polyester synthesis process single change variables as catalyst, esterification, condensation, was studied using the control variables method, with a esterification temperature, condensation temperature, by generating color and water amount of data, so as to find out the synthesis of dendritic PBS optimum conditions. The succinate, butanediol, propylene glycol, dual catalyst （of toluene sulfonic acid and stannous chloride） and 50 mL of toluene were added to three mouth flask. Using dual catalyst, the optimum temperature was 130 ℃, the optimal reaction time was 1.0 h, optimal polycondensation temperature was 220 ℃, the optimal polycondensation time was 3.0 h.
