It is preferred to describe the Rouse time, t R, in terms of parameters that do not … Webtime-scale contributions due to the glassy modes must be eliminated. The TAOrchestrator software accomplishes this by first crudely estimating the MWD. From the estimated MWD, the Rouse-like glassy response is estimated by summing the all Rouse modes for all components of the MWD and subtracting this contribution from G(t).

WebA lattice Monte Carlo study of the self-diffusion of polymer chains in an athermal solution of equal chains is presented. The examined chain lengths, N (= 20–200), and volume fractions, φ (= 0.025-0.5), cover the range from dilute solution to concentrated solution, respectively. The dynamics show a gradual crossover from Rouse to reptation-like behaviour. … WebSep 1, 2024 · In this article, we propose a model of the Rouse model type, which includes the viscoelastic effects.
