Methods of making polymers with reduced tack, and rubber compositions incorporating these polymers
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.
