Abstract: Embodiments of the present disclosure are directed to functionalized copolymers produced by copolymerization of at least one conjugated diolefin monomer and at least one vinyl monomer, the functionalized copolymer including at least one functional group having silica reactive moieties, wherein the functionalized copolymer has a degree of hydrogenation of 75% to 98 mol % as measured using proton nuclear magnetic resonance spectroscopy (1H NMR). In one or more embodiments, the silane modifier may include an oxygen-containing moiety, wherein the oxygen atom of the oxygen-containing moiety may not be directly bonded with the silicon atom.
