| Research Abstract |
In this research direct observation of the dynamic heterogeneity has been tried using X-ray diffraction coupled with temperature modulation technique which has been developed as a technique for thermal analysis. An experimental system was successfully developed, however, the heterogeneity could not be observed. It has been considered that the reason of the failure was the one dimensional shape of the dynamically heterogeneous regions as proposed recently. It was found that the temperature modulated X-ray experiment was very useful in studies of the structure of semi-crystalline polymers.
