Micelles were self-assembled from cyclic and linear amphiphilic block copolymers with a poly(ethylene oxide) hydrophilic segment and poly(methyl acrylate) or poly(n-butyl acrylate) hydrophobic segments. Turbidity measurements showed that the micelles formed from the cyclic amphiphiles have higher thermal stability than those formed from the linear counterparts. The mechanism for the enhanced thermal stability was studied by temperature-dependent 1H NMR relaxometry to evaluate the mobility of the respective hydrophilic and hydrophobic segments.
