Document Type and Number:
WIPO Patent Application WO/2017/104423
Kind Code:
A1
Abstract:
In the present invention, a rubber composition in which wear resistance and low heat-generating properties are obtained to a higher degree at the same time is provided through use of a rubber composition characterized by being obtained by blending a rubber component A including natural rubber and a modified conjugated diene (co)polymer having a glass transition temperature of -50°C or below, a rubber component B having a glass transition temperature of -35°C or higher, and a reinforcing filler, the modified conjugated diene (co)polymer having at a terminal end of the conjugated diene (co)polymer molecule a silanol group and a functional group which is near the silanol group and promotes reaction between the silanol group and the reinforcing filler, and two peaks based on the rubber component A and the rubber component B, respectively, being observed in a tan δ temperature dispersion curve obtained by a dynamic viscoelasticity test.
