| Outline of Final Research Achievements |
Phase transitions between crystalline structures are well known, and the changes of physical properties that accompanies the transitions have been extensively studied. Recently it has been widely accepted that even liquids can have several structures and there can be phase transitions between liquid structures. In this study, we aim to prove that there are such liquid-liquid phase transitions in polymer melts, and found pressure-induced structural changes in some polymer melts. We also tried to create two amorphous solids by one polymer, which are stable at room temperature and atmospheric pressure.
