Abstract

Back Cover: The carboxy-betaine polymer shows pH-responsive behavior. Above pH 4, the carboxy-betaine polymer becomes cationic polymer due to protonation of the pendant carboxy group. In article 2400532, Shin-ichi Yusa and co-workers have prepared dual zwitterionic diblock copolymers composed of carboxy- and phospho-betaine blocks. At acidic conditions, pH-responsive polyion complex (PIC) micelles are formed by dual zwitterionic diblock copolymers and anionic diblock copolymers due to electrostatic interactions.

ph响应型羧甜菜碱块水溶性多离子络合物胶束的制备

后盖：羧基甜菜碱聚合物显示ph响应行为。当pH值高于4时，由于羧基的质子化作用，羧基甜菜碱聚合物变成阳离子聚合物。在文章2400532中，Shin-ichi Yusa等人制备了由羧基和磷酸甜菜碱嵌段组成的双两性离子双嵌段共聚物。在酸性条件下，双两性双嵌段共聚物和阴离子双嵌段共聚物由于静电相互作用而形成ph响应型多离子络合物（PIC）胶束。
