| Research Abstract |
We have made an approach to the melting kinetics of polymer crystals in order to establish the measurement and analysis methods of the crystal melting, which determines the heat resistance of crystalline polymeric materials. In particular, we have examined isotactic polypropylene and polyethylene, which are required further improvements of the properties and functionalities. In order to remove the influence of re-organization on melting, we have examined the melting behaviors by means of ultra-fast-heating thermal analysis up to 10,000K/s. Based on the quantitative evaluation of the melting kinetics, we have successfully proposed the determination method of the equilibrium melting point and experimentally confirmed the applicability.
