Abstract: : Quantifying the response of entangled polymers to large and rapid deformations presents a great challenge in polymer physics. With simulation results, we identify the effective entanglement that governs the chain conformation and rheological response… read more here.

Abstract: The constraint release (CR) mechanism has important effects on polymer relaxation and the chains will show different relaxation behaviour in conditions of monodisperse, bidisperse and other topological environments. By comparing relaxation data of linear polyisoprene… read more here.

DOI: 10.1122/1.5031072
Abstract: We study the interaction between constraint release and contour length fluctuations in well entangled polymers, by means of a set of slip-spring simulations in which the rate of constraint release is precisely controlled. In the… read more here.
