| Outline of Final Research Achievements |
Entangled polymer chains relax by escaping from the entanglements by reptation motion under equilibrium. If flow faster than this relaxation is applied, it is believed that the chains are pulled out from the entanglements by flow and the relaxation is accelerated. This acceleration (known as CCR) is now considered as an essential ingredient of the polymer dynamics. In this study, we have shown by numerical simulation that stress and dielectric relaxations are indeed accelerated by flow. It is also found that polymer chains are rotating under shear flow, with the rotation frequency proportional to the square root of the shear rate.
