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.
