摘　　要：以偏苯三酸酐,环氧氯丙烷和季戊四醇为原料合成超支化聚酯,采用聚乙二醇(PEG)对合成的超支化聚酯进行改性。通过红外光谱、凝胶渗透色谱等对合成的聚醚改性超支化聚合物进行表征,研究了合成聚合物的表面活性,结果表明:采用PEG600、PEG800和PEG1000对超支化聚合物进行改性得到的聚合物具有良好的表面活性,25℃时它们的临界胶束浓度分别为0.00075g/mL、0.01517g/mL和0.033g/mL。Starting from trimellitic anhydride, epichlorohydrin and pentaerythritol, hyperbranched polyester was synthesized,and then was modified by polyethylene glycol（PEG）. The polymer was characterized by FT-IR, GPC and its surface activity was studied. The result revealed that the polymer modified by PEG600 ,PEG800 and PEG1000 possessed fa vorable surface activity. Their corresponding critical micelle concentration at 25℃ were 0. 00075,0. 01517 and 0. 033g/ml respectively. Key Words hyperhranched polymer, modificatian, surface activity.
