Ft-Ir Study of the Dynamics of Entangled Polymer Melts
The dynamics of entangled polymer melts have been examined using polarized Fourier-Transform infrared (FT-IR) spectroscopy. Based on the reptation model, the motion of a chain in the presence of topological entanglements is that of a one dimensional random walk along the chain contour. This motion …

Rheological inferences with uncertainty quantification
… ideas of previous part to fit the data on two entangled polyethylene melts: a linear polyethylene melt and its blend with a three-arm symmetric star polymer (5 weight % of star by composition). We show that the simplest model for entangled polymer melts i.e. the Doi-Edwards reptation model is …

Theories of slow dynamics: from glassy colloidal suspensions to entangled macromolecular liquids
… slowing down of dynamics in glassy and polymeric fluids, microscopic theories for the dynamical behavior of these systems are explored. Of particular interest is the relative importance of equilibrium structure and topological constraints on system dynamics, and theories studying each …
