    摘要： A process for producing a conjugated diene copolymer rubber which comprises: initiating a copolymerization reaction in a reaction system containing a first conjugated diene compound and a first aromatic vinyl compound and completing the reaction; adding a first polyfunctional monomer to the reaction system, optionally further adding a second conjugated diene compound and a second aromatic vinyl compound, and further conducting copolymerization; and subsequently adding a modifier to the reaction system to react them. Thus, a rubber composition can be obtained which has satisfactory processability and comes through vulcanization to have sufficient hardness and reduced rolling resistance.

    摘要： A rubber composition that can obtain a rubber elastic body having small rolling resistance and excellent impact resilience and a method for producing the same, and a tire having small rolling resistance and excellent impact resilience are provided. The rubber composition of the present invention is obtained by kneading a conjugated diene polymer having a functional group bondable to silica, an acylate compound containing metal and silica. In the present invention, a polymer having no functional group bondable to silica is preferably kneaded as a rubber component other than the conjugated diene polymer, together with the conjugated diene polymer having a functional group bondable to silica, the acylate compound containing metal and the silica.
