ABC-type miktoarm star copolymers are synthesized using a single living radical polymerization (organocatalyzed living radical polymerization) via a "combinatorial" approach. The arm A is poly(butyl acrylate), the arm B is poly(methyl methacrylate), and the arm C encompasses hydrophobic and hydrophilic polyacrylates. A poly(butyl acrylate) with a vinyl chain end (macromonomer) is synthesized. A poly(methyl methacrylate) is subsequently connected to the reactive vinyl group to generate diblock copolymer. From the junction of the diblock copolymer, polymer C grew to yield star copolymers. An amphiphilic star copolymer is also synthesized, and its self-assembly structure is studied in an aqueous solution.

通过有机催化活性自由基聚合合成ABC Miktoarm星型共聚物。

使用单一的活性自由基聚合(有机催化的活性自由基聚合)通过“组合”方法合成ABC型拟臂星形共聚物。臂A是聚丙烯酸丁酯,臂B是聚甲基丙烯酸甲酯,并且臂C包括疏水性和亲水性聚丙烯酸酯。合成具有乙烯基链端的聚丙烯酸丁酯(大分子单体)。随后将聚(甲基丙烯酸甲酯)连接至反应性乙烯基,以生成二嵌段共聚物。从二嵌段共聚物的交界处,聚合物C生长以产生星形共聚物。还合成了两亲性星形共聚物,并在水溶液中研究了其自组装结构。
