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 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.

摘要： Block copolymers are described which comprise alternating blocks of (A) a polysiloxane; and (B) a copolymer of a 1,3-conjugated diene and a monovinyl aromatic compound. The block copolymers can be prepared by reacting a polysiloxane with a dilithiated copolymer of a conjugated diene and a monovinyl aromatic compound and thereafter neutralizing the reaction product with a protonic acid or a polyfunctional alkyl silane or silicon tetrachloride. Cured elastomer compositions exhibiting surface release characteristics are obtained by curing a mixture comprising the above-described block copolymer in the presence of a curing system comprising a peroxide and sulfur. Multilayer elastomer structures useful in manufacturing articles from elastomeric materials also are described wherein at least a portion of an outer layer of the multilayer elastomer structure has release characteristics and comprises the cured block copolymers of the present invention.
