摘要： 一种新型的两亲性多杂臂超支化聚缩水甘油(HPG-h-arm)可以通过简单的三部反应制备: 先利用阴离子开环聚合制备HPG核, 再利用1,3-二环己基碳化二亚胺(DCC)缩合反应一步同时将疏水性的棕榈酸(PA)链和活性溴接枝到HPG上面, 最后利用原子转移自由基聚合反应(ATRP)将亲水性的聚(N,N-二甲氨基甲基丙烯酸乙酯) (PDMAEMA)链接枝到HPG表面. 红外光谱(FTIR), 核磁共振(1H-NMR)和凝胶渗透色谱仪(GPC)证实了HPG-h-arm被成功制备. 利用动态光散射仪(DLS), 透射电子显微镜(TEM)和原子力显微镜(AFM)研究了HPG-h-arm在不同溶剂中的自组装行为和形貌. 结果表明HPG-h-arm在不同的溶剂中可以自组装得到不同尺寸的球状胶束.

Abstract: A novel multihetero-arms hyperbranched polyglycerol (HPG-h-arm) was synthesized through facile three steps: synthesis of HPG by anionic ring-opening polymerization of glycidol, grafting hydrophobic palmitic acid (PA) chains and reactive Br by N,N’-dicyclohexylcarbodiimide (DCC) coupling reaction, and grafting hydrophilic poly(2-(dimethyl amino)ethyl methacrylate) (PDMAEMA) chains by atom transfer radical polymerization (ATRP). The structure of the HPG-h-arm was characterized by FTIR and 1H NMR. The self-assembled behaviors of the HPG-h-arm in different solvents were detected by DLS, and the morphology of the assembly was examined by TEM and AFM. The results showed that the HPG-h-arm could form spherical micelles with different sizes in different solvents.
