报道了一种界面接枝自由基聚合法制备两亲性梳状共聚物和壳层交联聚合物纳米胶囊的方法。在水相中用过氧化氢在水溶性长链多胺上产生大分子聚合自由基，随后在65°C下在水/油界面进行乙烯基单体的接枝自由基聚合。在交联剂的存在下，所得接枝共聚物形成具有由多胺官能化的亲水性水性核和疏水性交联聚合物壳的限定的核-壳结构。采用NMR、FTIR、DSC、TGA、SEM、TEM等手段对核壳材料的结构进行了表征，并对接枝聚合机理进行了探讨。© 2007 Wiley Periodicals，Inc.应用聚合物科学杂志104：1905-1911，2007
An interfacial grafting radical polymerization method for amphiphilic comb copolymer and shell crosslinked polymer nanocapsules was reported. Macropolyradicals on a water soluble long chain polyamine were generated with hydrogen peroxide in the water phase and subsequent grafting radical polymerization of a vinylic monomer at the water/oil interface proceeded at 65°C. In the presence of a crosslinker, the resulting graft copolymer formed a defined core-shell structure with hydrophilic aqueous core functionalized by the polyamine and a hydrophobic crosslinked polymer shell. The structure of the core-shell material was characterized by NMR, FTIR, DSC, TGA, SEM, TEM, and the mechanism of the graft polymerization is proposed. © 2007 Wiley Periodicals, Inc.
