| Research Abstract |
Dynamics of branch polymers is an important subject not only in polymer science but also in industry to design processability of materials. In this study we applied our coarse-grained molecular simulation to branch polymers to evaluate the model and to investigate the dynamics around branch point. The simulation realized quantitative predictions on linear and non-linear viscoelasticity of branch polymers and showed significance of dynamic tube dilation around branch point.
