    • This invention provides a process for producing a conjugated diolefin (co)polymer rubber, which does not rely upon the type and combination of compounding fillers, is excellent processability, and, upon vulcanization to provide vulcanized rubber, has excellent balance among wet skid properties, low hysteresis loss, abrasion resistance, and breaking strength and is useful as a tread material and a side wall member in fuel-efficient tires, large tires and high-performance tires. In the production process of a conjugated diolefin (co)polymer rubber, a conjugated diolefin or a combination of a conjugated diolefin with an aromatic vinyl compound is anionically polymerized in the presence of an initiator, which is at least one compound selected from the group consisting of organic alkali metals and organic alkaline earth metals, in a hydrocarbon solvent. Thereafter, the living polymer in its end is reacted with a polyisocyanate compound, and the residual isocyanate group in the polyisocyanate compound attached to the end of the living polymer is reacted with an alkoxysilane compound containing an active hydrogen-containing functional group. There is also provided a conjugated diolefin (co)polymer rubber produced by this process.
