| Outline of Final Research Achievements |
Aiming at the development of first-principle method to design high functional materials of crystalline polymers, we made molecular dynamics investigations on both the universal and the specific aspects of polymer crystallization. In order to study the universal aspects of polymer crystallization, we made use of the polyethylene-like polymer and investigated its crystallization from the quiescent melt state. We revealed various interesting characteristics of polymer crystallization that are considered universal in all linear polymers. We also studied the specific modes of crystallization in helical polymers, especially in isotatctic polypropylene, with special concern on the molecular mechanism of helix recognition. The molecular dynamics method was also shown to be of great potential in studying the effect of flow-fields or solid-substrates on polymer crystallization.
