Research Abstract

It is still difficult to get the qualified X-ray diffraction data of polymer crystals useful for the quantitative discussion of relationship between structure and physical properties. For these several years we have been making efforts to develop an X-ray structural analysis system equipped with an imaging-plate detector which is highly sensitive and highly quantitative. In this study, for supporting this new system, we have focused our attention onto the electron diffraction data. The polymer single crystals, grown from the dilute solutions, are quite small in size, only a few micrometer, but give beautiful diffraction patterns consisted of many sharp spots. If we can analyze these diffraction patterns in enough quantitative manner, then we should have the highly accurate structural information on polymer crystals. But this type of technique has not yet been enough established. Our main purpose is to develop a new system powerful for solving these problems. The electron microscope was installed, to which the imaging plate was set. A new software was created which was found to be quite useful for the quatitative analysis of the position and integrated intensity of the observed reflections. The actual application of this method has been made successfully to n-alkane crystals and so on : the initial structures could be extracted by the direct method and be refined well.
