Research Abstract

In order to clarify the shish-kebab formation process, we carried out the quantum beam analysis and FT-IR measurements. Especially, the effects of molecular weight on the shish-kebabs and conformational changes were focused on. By neutron and synchrotron radiation x-ray scattering measurements, we observed the oriented structure of low molecular weight component with about 1 micron. From FT-IR measurements, we succeeded the conformation of precursors, which has crystalline conformations.
