通过Friedel-Crafts反应将氯甲基引入氢化聚苯乙烯-嵌段-丁二烯-嵌段-苯乙烯（SEBS）的聚苯乙烯（PS）嵌段中。产物（SEBS-CH_2Cl）在THF/乙醇（10/9，v/v）中形成了以PS为冠、以氢化PB为核的球形胶束。然后，以1，6-己二胺为交联剂，通过胺化使带有CH 2Cl基团的聚苯乙烯电晕交联。壳交联胶束呈球形核壳结构，在溶液中是稳定的，这是通过DLS在溶液中和TEM在固态下验证。
Chloromethyl groups were introduced into the polystyrene (PS) blocks of hydrogenated poly(styrene-block-butadiene-block-styrene) (SEBS) via Friedel–Crafts reaction. The product (SEBS-CH2Cl) formed spherical micelles with PS corona and hydrogenated PB core in THF/ethanol (10/9, v/v). Then, the polystyrene corona carrying CH2Cl groups was cross-linked by amination with 1,6-hexanediamine as a cross linker. The shell cross-linked micelles showed spherical core-shell structure and were stable in solution, which was verified by DLS in solution and by TEM in the solid state.
