Abstract: Abstract We extensively study the polymer chain packings of various entangled polymer systems. Surprisingly, the number of entanglement strands per cubed tube diameter does not obey the overlap criterion for entanglement. By analyzing microscopic topology… read more here.

Abstract: One of the most important nonlinear rheological phenomena in flowing polymeric materials is the stress overshoot under start-up shear at sufficiently high shear rates γ, i.e., γ > τd–1, where τd is the terminal relaxation… read more here.
