Variable-temperature dynamic light scattering (DLS) studies showing the variation of hydrodynamic diameter (blue ▲) and polydispersity (red ■) for a 0.10% w/w PLMA₁₆–PBzMA₃₇ dispersion in n-dodecane on heating from 20 to 90 °C (filled symbols) and on cooling from 90 to 20 °C (open symbols). Representative transmission electron microscopy (TEM) images obtained for the same dilute dispersion are shown as insets. These data confirm the irreversible nature of the worm-to-sphere transition that occurs on heating PLMA₁₆–PBzMA₃₇ under these conditions.
