Document Type and Number:
WIPO Patent Application WO/2011/125637
Kind Code:
A1
Abstract:
Disclosed is a rubber composition that when made into a tire improves durability such as wear resistance, tear resistance, and the like, and that enables a reduction in rolling resistance, by using a rubber composition that includes: a rubber component comprising a conjugated diene polymer that includes at least one selected from a silicon atom, a tin atom, a sulfur atom, an oxygen atom, and a titanium atom in either a polymerization-active terminal, a polymerization initiating terminal, or a polymer chain, and a carbon black used for rubber compounding that was obtained by using a reactor comprising a combustion gas generation zone, a reaction zone, and a reaction termination zone provided in a linked manner, generating a high-temperature combustion gas within the aforementioned combustion gas generation zone, and subsequently spraying a starting material into the aforementioned reaction zone and quenching a reactant gas stream comprising a carbon black to terminate the reaction, wherein the aforementioned carbon black used for rubber compounding satisfies specific relations (1) and (2). Also disclosed is a tire using the same.
