Elastomers having a reduced hysteresis via interaction of polymer with silica surfaces |
摘要 |
The reduction of hysteresis in a silica-filled, vulcanized elastomeric compound is produced by mixing diene monomer and optionally monovinyl aromatic monomer with an initiator and a coordinator; effecting polymerization conditions; terminating polymerization with a terminator containing an organo-tin group to form a tin-coupled diene elastomer; compounding the tin-coupled 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.
