| Outline of Final Research Achievements |
Nowaday polymeric materials are indispensable in our daily life. To manufacture sophisticated polymer products, it is necessary to predict and control their flow behaviors in industrial processes. However, this is in general very difficult because the microscopic state of polymer chains and the macroscopic polymeric flow are tightly connected each other. Therefore, in this project we have developed an extended theoretical method where a small number of essential microscopic degrees of freedom are included. By using this method, we investigated the ordering dynamics of a block-copolymer melt.
In addition, we have also developed a multiscale simulation method for a polymer melt spinning process. Through simulations performed using this method, we have succeeded in predicting the microscopic state of polymer chains on an arbitrary position along the spinning line and the relation between this state and the corresponding flow behavior of spinning.
