Abstract
The reduction of hysteresis in a silica-filled, vulcanized elastomeric compound is produced by mixing diene monomer and optionally monovinyl aromatic monomer with a lithium amine initiator and, optionally, a modifier; effecting polymerization conditions; terminating polymerization with an amino group producing terminator to form an amine functionalized diene elastomer; compounding the amine functionalized diene elastomer with an amorphous silica filler and a vulcanization agent; and, effecting vulcanization. A pneumatic tire tread stock incorporating the vulcanized elastomer compound exhibits decreased rolling resistance in the tire.
