| Outline of Final Research Achievements |
The molecular mechanism of the glass transition has not been understood. This work is aimed to elucidate the glass transition mechanism through experimental studies to measure the time (tau_tau) necessary for the relaxation time of the alpha process to reach the new value after quick temperature change and its temperature dependence. A new experimental instrument, temperature modulated non-linear dielectric spectroscopy, has been developed. It was found that the tau_tau was ca. 1 s around the glass transition temperature and its temperature dependence was close to Arrhenius type. These results were obtained firstly in the world and will stimulate the studies on the glass transition in future.
