Article   M. Kröger, S. Hess
Rheological evidence for a dynamical crossover in polymer melts via nonequilibrium molecular dynamics
Phys. Rev. Lett. 85 (2000) 1128-1131
A certain `critical' molecular weight controls rheological properties of the multibead finitely extensible nonlinear elastic (FENE) chain model polymer melt. The rheological crossover manifests itself in a change of power law behavior for the viscous properties at a critical number of beads per chain Nc=100 +/- 10. This finding confirms a newly proposed relationship between dimensionless critical weight, characteristic length and flexibility which we obtain as a side-result. Results further suggest, that the entanglement molecular weight Ne for the flexible FENE chain model could be comparable in size or even larger than its critical molecular weight Nc.
