    摘要: An anionic polymerization initiator comprising the reaction product of a functionalizing agent selected from the group consisting of substituted aldimines, ketimines and secondary amines and, an organolithium compound. Elastomeric polymers prepared with these initiators have functional sites incorporated at the initiator end of the polymer chain and provide vulcanizable rubber compounds exhibiting reduced hysteresis. Articles such as tires, produced with low hysteresis elastomeric polymers have lower rolling resistance. Methods are also provided for preparing the initiators, functionalized polymers and vulcanizable elastomeric compounds having reduced hysteresis.

    摘要: An anionic polymerization initiator includes a carbon-lithio salt of the adduct of a cyclic secondary amine with a conjugated diene. A method of preparing an anionic polymerization initiator includes reacting an excess of a cyclic secondary amine with a conjugated diene to form an adduct; and, reacting the adduct with an organolithium compound. A method of preparing a polymer includes forming a solution of one or more anionically polymerizable monomers in a hydrocarbon solvent; and, polymerizing the monomer with an anionic polymerization initiator comprising a carbon-lithio salt of the adduct of a cyclic secondary amine with a conjugated diene. A functionalized polymer includes the termination product of a living polymer having the general formula AYLi, wherein A is a functional group derived from an anionic polymerization initiator; and, Y is a divalent polymer radical; wherein the anionic polymerization initiator is a carbon-lithio salt of the adduct of a cyclic secondary amine with a conjugated diene.
