Document Type and Number:
Japanese Patent JP6915242
Kind Code:
B2
Abstract:
Provided are a rubber composition having excellent wear resistance, a production method therefor, and a method by which the wear resistance of a rubber composition can be evaluated with high accuracy. The present invention is directed to a rubber composition in which a relationship between: a maximum value c of a correlation length i of 10 nm to 100 µm obtained by performing curve-fitting with specific expressions on a scattering intensity curve I(q) obtained by performing X-ray scattering measurement or neutron scattering measurement in a specific region; and a standard deviation à c of the maximum value c is à c ¤ c /2, and in which a filler dispersibility index G* obtained by a specific expression is not greater than 3.
