| Research Abstract |
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.
