Title:
RUBBER COMPOSITION FOR TIRES, AND PNEUMATIC TIRE MANUFACTURED USING SAME
Document Type and Number:
WIPO Patent Application WO/2015/029909
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a rubber composition for tires, which has excellent rubber properties. The present invention relates to: a rubber composition for tires, which comprises a diene rubber and a composite silica comprising a block copolymer and silica, wherein the block copolymer has a first block produced by polymerizing a first monomer comprising at least a (meth)acrylate having a hydroxy group and a second block produced by polymerizing at least one second monomer selected from the group consisting of styrene, a derivative thereof and isoprene, and wherein the composite silica is produced in an organic solvent in the presence of the silica, and the amount of the composite silica is 10 to 200 parts by mass relative to 100 parts by mass of the diene rubber; and a pneumatic tire which is manufactured using the rubber composition.
