Zwitterionic polymers are a distinctive class of materials with unique physical and chemical properties. In this study, the synthesis of fully zwitterionic ABA triblock copolymers was achieved by controlled radical polymerization using two different zwitterionic monomers, sulfobetaine methacrylate (SBMA) and 2-methacryloyloxyethyl phosphorylcholine (MPC). Due to the strong tendency of the sulfobetaine groups to aggregate, the fully zwitterionic triblock copolymers demonstrated self-assembly as well as salt and thermal responsiveness in solution.

完全两性离子三嵌段共聚物的合成与自组装

两性离子聚合物是一类独特的材料，具有独特的物理和化学特性。在这项研究中，完全的两性离子ABA三嵌段共聚物的合成是通过使用两种不同的两性离子单体，磺基甜菜碱甲基丙烯酸酯（SBMA）和2-甲基丙烯酰氧基氧乙基磷酰胆碱（MPC）进行受控的自由基聚合来实现的。由于磺基甜菜碱基团聚集的强烈趋势，完全两性离子三嵌段共聚物在溶液中表现出自组装以及盐和热响应性。
