Zusammenfassung:Embodiments of the present disclosure are directed to methods of preparing an alkoxysilane functionalized polymer, the method comprising: introducing an anionic polymerization initiator to a reactor comprising a reactive mixture including conjugated diolefin monomer and solvent to form a living polymer via anionic polymerization; introducing alkoxysilane to the reactor to mix with the living polymer to form an alkoxysilane functionalized polymer; adding at least one aliphatic carboxylic acid having at least 10 carbons to the alkoxysilane functionalized polymer; and removing solvent from the alkoxysilane functionalized polymer.
