Abstract
Official abstract text for this publication.
Provided is a rubber composition that achieves a balanced improvement in fuel economy, abrasion resistance, and wet grip performance while having good processability. Also provided is a pneumatic tire including a tread formed from the rubber composition. The present invention relates to a rubber composition containing: a rubber component including a copolymer; and carbon black and/or silica, the copolymer containing a structural unit derived from a conjugated diene monomer and a structural unit derived from a compound represented by the following formula (1): wherein R 11 represents a C1-C30 hydrocarbon group.
First claim
Opening claim text (preview).
The invention claimed is: 1. A pneumatic tire, comprising a tread formed from a rubber composition, the rubber composition comprising: a rubber component comprising a copolymer; and at least one of carbon black or silica, the copolymer containing a structural unit derived from a conjugated diene monomer and a structural unit derived from a compound represented by the following formula (1): wherein R 11 represents a C3-C30 hydrocarbon group. 2. The pneumatic tire according to claim 1 , wherein the copolymer contains, based on 100% by mass of structural units of the copolymer, 5% to 95% by mass of the structural unit derived from a conjugated diene monomer and 5% to 95% by mass of the structural unit derived from a compound of formula (1). 3. The pneumatic tire according to claim 1 , wherein the copolymer has a weight average molecular weight of 5,000 to 2,000,000 and a molecular weight distribution of 2.1 to 11. 4. The pneumatic tire according to claim 1 , wherein the compound of formula (1) is vinyl cinnamate. 5. The pneumatic tire according to claim 1 , wherein the conjugated diene monomer is 1,3-butadiene. 6. The pneumatic tire according to claim 1 , wherein the copolymer has at its end a functional group having an affinity for filler.
