以1,2,4-苯三酸酐和聚乙二醇(聚乙二醇300、聚乙二醇400、聚乙二醇600)为反应单体, 首次通过缩聚法合成了一系列两亲性芳香族超支化聚酯. 通过FT-IR、1H NMR、GPC、DSC、TGA对超支化聚酯的结构和性能进行了表征, 结果表明, 利用缩聚法成功合成了两亲性超支化聚酯, 并且两亲性超支化聚酯的热性能稳定. 两亲性超支化聚酯在水中自组装成囊泡, 可以用作微反应器和药物封装等.

关键词: 缩聚, 超支化聚酯, 自组装, 囊泡

A series of amphiphilic aromatic hyperbranched polyesters (HBPEs) were firstly synthesized by way of polycondensation with 1,2,4-benzenetricarboxylic anhydride (BTAA) and polyethylene glycol (PEG300, PEG400, PEG600). Structure and property of HBPEs were characterized by FT-IR, 1H NMR, GPC, DSC and TGA. The obtained HBPEs have a good thermal stability and can self-assemble into vesicles in water. These vesicles might be applied as microreactors or drug carriers etc.

Key words: polycondensation, hyperbranched polyesters, self-assembly, vesicles
