| 摘 要： | 以苯乙烯(St)、马来酸酐(MA)、香豆素苯乙烯醚化物(CS)为单体, 通过自由基溶液聚合合成了双亲性交替共聚物P(St/CS-alt-MA), 用凝胶渗透色谱、核磁共振等对聚合物结构进行表征, 并对其溶液自组装及组装体的乳化性进行了研究. 结果表明双亲性P(St/CS-alt-MA)可以在选择性溶剂中进行自组装形成马来酸酐单元为亲水微区、CS与苯乙烯单元为疏水微区的胶体粒子, 用紫外分光光度计, XPS, TEM研究了聚合物胶体粒子性质, 结果显示, P(St/CS-alt-MA)在水溶液中可以形成两亲性聚合物胶体粒子, 亲水单元在胶粒表面富集, 该两亲性聚合物胶体粒子具有良好的乳化性能.

| Abstract: | A new amphiphilic alternating copolymer P(St/CS-alt-MA) was prepared through free radical copolymerization. The copolymer structure was examined by GPC and 1H NMR. The amphiphilic copoly-mer could aggregate into nanoparticles in selective solution. The micellization and the critical water content (CWC) of P(St/CS-alt-MA) in deionized water were monitored by UV-Vis spectroscopy. The diameters and morphologies of the particles were examined by TEM and XPS. The results show that hydrophilic units are enriched ... |
