Abstract

A terminally functionalized polymer is prepared by reacting a living polymer obtained by anionic polymerization of a diene monomer or mixture of a diene monomer and a vinyl aromatic hydrocarbon monomer with a fused-ring polynuclear aromatic compound. The resultant terminally functionalized polymers have reduced hysteresis in the carbon black reinforced and cured state and can be utilized to form elastomer compositions for tire treads having reduced rolling resistance.
