Title:

ゴム組成物

Document Type and Number:

Japanese Patent JP7315409

Kind Code:

B2

Abstract:

To provide a rubber composition that has good processability, has good dispersibility of a filler by allowing the composition to achieve a relatively high rate of torque rise and be easily kneaded particularly when kneading a rubbery polymer with a filler by a mixer and is excellent in low hysteresis loss property.SOLUTION: The rubber composition includes 100 pts.mass of a rubbery polymer and 5 to 150 pts.mass of a filler. The rubbery polymer includes at least two kinds of modified conjugated diene-based polymers (A) and (B) in which the content of the modified conjugated diene-based polymer (A) in the rubbery polymer is 30 mass% or more and the modified conjugated diene-based polymers (A) and (B), respectively, have specific characteristics.SELECTED DRAWING: None
