Research Abstract

Anomalous Small-Angle X-ray Scattering at Sulfur K-edge was developed at BL27SU, SPring-8. By using this technique, structural distribution of sulfur in rubber was analyzed. Optimization of detectors and measurement protocol enabled us to measure scattering intensity profiles with a sufficiently high signal-to-noise ratio to investigate the energy dependence of the profiles. Based on the result, a model for sulfur distribution in rubber was proposed.
