摘　　要：以椰子油脂肪酸二乙醇酰胺（CDEA）和2,2G双（羟甲基）丙酸（DMPA）为原料,对甲苯磺酸（pGTSA）为催化剂,采用“一锅煮”法合成了1-3代端羟基超支化聚合物.通过单因素实验优化了合成条件：反应温度160℃,反应时间4h,催化剂用量为1%（以CDEA 质量计）.通过FTGIR和1H NMR对产物的结构进行了表征,并测定了其表面活性.结果证明,该系列超支化聚合物具有不同的表面活性,可以根据需要,通过超支化改性的方式改变表面活性剂的表面活性.Hydroxyl terminated hyperbranched polyesters of generations 1-3were synthesized by one-pot method using coconut-oil fatty acid diethanolamide(CDEA)with dimethylol propionic acid(DMPA)as monomers,ptoluenesulfonic acid(p-TSA)as catalyst.The appropriate reaction conditions were optimized by single factor experiments as follows.The reaction temperature was 160℃,the reaction time was 4hand the quantity of catalyst was equal to 2% of feedstock.The molecular structures of the products were characterized by FT-IR and1 H NMR while surface activities were measured by more than one standard.The results showed that different properties of the modified surfactants were obtained using hyperbranched structure.
