| Research Abstract |
For silica-filled SBR rubber, which is widely used for fuel-efficient tire, small-angle neutron scattering measurements were conducted under the contrast varied states by proton spin polarization. In conventional measurements, because of the overlap of scattering contributions due to multiple components in rubber, it is difficult to determine structural parameters precisely. However, by use of proton spin contrast variation technique, we succeeded in abstracting scattering contribution only due to silica component, whose dispersion is known to be a key factor for fuel-efficiency.
