Polyoxazolines (POx) are well known thermoresponsive polymers, which exhibits 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 the both initiation and termination ends through the living polymerization process. We can utilize functional initiators to introduce specific functional groups at initiation end. Alternatively, termination end can be easily modified by treating with functional nucleophile to the living cationic terminal. Using those properties, recently, we have designed redox-active POxs that exhibited color and thermal transition temperature changes by redox potential application. |
