| In this work, we present rheological results from long Molecular Dynamics (MD) simulations of linear monodisperse polyethylene (PE) chains with lengths ranging from 0.5 to 17.5 entanglements at equilibrium. The viscosity, relaxation modulus, plateau modulus, selfdiffusion coefficient and the dynamic structure factor obtained from present simulations and their scalings with molecular weight are in very good agreement with experimental data. We also present some preliminary analysis of the dynamical trajectories in the framework of the tube theory and attempt to extract the corresponding parameters of the model. | |
