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创造了新的热敏聚合物，在水或各种有机溶剂中表现出较高的临界溶液温度型相分离。用一系列带氨基基的两亲嵌段共聚物研究了其抗菌和溶血活性。在适宜的反应条件下，实现了乙烯醚与多种醛的可控交替共聚，得到了具有高选择性酸降解性的共聚物。此外，还证明了星形聚合物的高效、简便的一步合成。
