Abstract
A method for producing an alkoxysilyl group-containing conjugated diolefin (co)polymer rubber by polymerizing a conjugated diolefin or a conjugated diolefin and an aromatic vinyl compound in a hydrocarbon solvent by anionic polymerization using as an initiator at least one metal compound selected from an organic alkali metal compound and an organic alkali earth metal compound, and then allowing an alkoxysilane-based compound to react, wherein after the alkoxysilane-based compound has been allowed to react, an alkaline compound is added at the time of desolvation, and treatment is conducted at a pH of 8 to 12.
