Rubber composition and pneumatic tires |
| abstract |
Provided is a practical rubber composition for a tire capable of suppressing an increase in tan δ near 60 ° C. while improving tan δ near 0 ° C. of the tire. A rubber composition containing a diene-based rubber and a liquid crystal polymer having a phase transition temperature (Ti) between a liquid crystal phase and an isotropic phase of 20 ° C. or less, and the liquid crystal polymer has an active hydrogen group. It is a polymerization reaction product of a mesogendiol, which is an addition reaction product of a mesogen group-containing compound, an alkylene oxide and / or a styrene oxide, and an isocyanate compound. |
