聚醚改性超支化聚合物的合成及性能
Synthesis and property of hyperbranched polyester modified with polyether
【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。
【Abstract】 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 PEG1000possessed favorable surface activity.Their corresponding critical micelle concentration at 25℃ were 0.00075,0.01517 and 0.033g/ml respectively.Key Words hyperbranched polymer,modification,surface activity.
