Title: METHOD FOR PRODUCING MODIFIED DIENE RUBBER, RUBBER COMPOSITION, AND TIRE
Abstract:
The present invention provides a method for efficiently producing a modified diene rubber, and a rubber composition and a tire which are excellent in low-loss properties, fracture characteristics, and the like. The modified diene rubber production method is characterized by comprising a modification step of adding a modifying agent to a raw-material diene rubber solution obtained by dissolving a raw-material diene rubber in a solvent, and reacting the raw-material diene rubber with the modifying agent while removing the solvent in the presence of applied mechanical shearing stress, to form a modified diene rubber. The rubber composition is characterized in that modified diene rubber produced by the modified diene rubber production method is employed. The tire is characterized in that the rubber composition is employed.
