Ring polymer has larger local domains of blocked segments, and thus narrower distributions of segmental mobility or weaker dynamical heterogeneity. Linear polymer has end segments with high mobility, which hindered the growth of local domains of blocked segments, and therefore wider distributions of segmental mobility, namely, stronger dynamical heterogeneity.
