| Outline of Final Research Achievements |
Dynamics of polymers under fast flows are of significant importance not only from scientific view point but also in industrial aspects, in which polymers in processing are subjected to fast flows. In this study, we attempt to investigate the segmental friction of polymers in oriented/stretched states that are realized under fast flows. In the conventional theories, the segmental friction has been assumed as of the equilibrium on the basis of the local equilibrium assumption. However, we have revealed that the friction depends on the magnitude of orientation and stretch of polymers, as a result of stretching experiments and molecular simulations. We have constructed the simulation scheme and the constitutive model incorporating the change of friction to describe the polymer dynamics under fast flow, and the rheology.
