Correction for ‘Finite cohesion due to chain entanglement in polymer melts’ by Shiwang Cheng et al., Soft Matter, 2016, 12, 3340–3351.
Nevertheless, the discrepancy between data and theory in ref. 5 did correctly suggest that it may be problematic to characterize the stress state and chain conformation on a default length scale of the equilibrium tube segment. A plausible picture may be that the characteristic structure of the entanglement network keeps evolving, e.g., the mesh size keeps growing over time both in startup and during relaxation from step strain. In any event, future MD simulations may provide clearer and more concrete pictures for nonlinear rheological behavior of entangled polymeric liquids.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
