Abstract
Polyoxazolines (POx) are well-known thermo-responsive polymers, which exhibit a reversible and rapid hydrophilic-hydrophobic interconversion through the lower critical solution temperature (LCST). Narrow molecular weight distributions of POx can be achieved by cationic living polymerization of oxazoline monomer. More importantly, we can easily introduce various functional groups to both initiation and termination ends through the living polymerization process. We can utilize functional initiators to introduce specific functional groups at the initiation end. Alternatively, the termination end can be easily modified by treating with functional nucleophiles to the living cationic terminal. Using those properties, we have designed various types of Pox-based functional materials showing thermos-responsive properties with photo-, redox-, electro-, and chemo-responsive properties. Moreover, we have fabricated network polymers using the redox-active POxs to achieve redox- and thermo-responsive shape changes in polymers. The details of POx-based polymers will be discussed in the symposium.
