Abstract

Rubber cross-linked by sulfur shows the higher physical properties than rubber cross-linked by peroxide. ZnO, stearic acid and vulcanization accelerator play the important role of vulcanization reaction. Previously, the many studies of vulcanization mechanism have been carried out, however, the precise mechanism of vulcanization mechanism with ZnO and vulcanized accelerator is not well understood. In order to investigate the detailed vulcanization mechanism, we measured the time-resolved XAFS during vulcanization at BL01B1 beam line, SPring-8. XAFS measurement is one of the powerful tools to obtain the electronic state and the structural information around the x-ray absorption atom. As the results of XAFS measurements, it was clearly observed that XAFS spectrum after vulcanization differ from that before vulcanization. We will be presented in this symposium.
