The precision synthesis via living cationic polymerization has created new thermosensitive polymers exhibiting an upper critical solution temperature-type phase separation in water or various organic solvents. The antibacterial and hemolytic activities were examined using a series of amphiphilic block copolymers with amino side groups. The controlled alternating copolymerization of vinyl ethers and various aldehydes was also achieved under appropriate reaction conditions, to produce copolymers with highly selective acid-degradability. Furthermore, highly effective and facile one-step synthesis of star-shaped polymers was demonstrated.

通过活性阳离子聚合的精密合成已经产生了在水或各种有机溶剂中表现出上临界溶液温度型相分离的新型热敏聚合物。用一系列带有氨基侧基的两亲性嵌段共聚物研究了其抗菌和溶血活性。在适当的反应条件下，还实现了乙烯基醚和各种醛的可控交替共聚，以生产具有高度选择性酸降解性的共聚物。此外，高效和方便的一步合成星形聚合物被证明。
