Ultrafast differential scanning calorimetry (UFDSC) is used to study the dynamics of phase separation in milliseconds by the virtue of small time and spatial resolution that UFDSC offers. The time scale of glass transition temperature (T g ) evolutions of samples were observed earlier than the patterns in the morphological methods at the early stage of the phase separation on page 1357 (DOI: 10.1002/polb.24378 ) by Dongshan Zhou and colleagues. This T g evolution behavior shows a distinct change when the phase separation mechanism changes from nucleation and growth (NG) to spinodal decomposition (SD). In the SD mechanism, the temperature‐dependent composition evolution in PVME‐rich domain was found to follow the Williams‐Landel‐Ferry (WLF) laws. (DOI: 10.1002/polb.24378 )
