(57) [Abstract] [PROBLEMS] A diene rubber excellent in heat generation, which is an index of rolling resistance, and also excellent in properties such as tensile strength, abrasion resistance, and workability, a method for producing the same, and a rubber composition containing the same. Provide things. SOLUTION: The conjugated diene bond unit is 40 to 99.99. % By weight, 0.05 to 20% by weight of silicon-containing vinyl-based monomer units such as alkoxysilyl groups, 0.05 by weight of amino-group-containing vinyl-based monomer units and / or hydroxyl-group-containing vinyl-based monomer units. A diene rubber having a Mooney viscosity (ML 1 + 4 , 100 ° C.) of 10 to 200% by weight, 20% by weight and other copolymerizable monomer units of 0 to 50% by weight. |
