    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.

    摘要: A terminally functionalized liquid polymer is prepared by reacting a low molecular weight living diene polymer or copolymer obtained by anionic polymerization of a diene monomer or mixture of a diene monomer and a vinyl aromatic hydrocarbon monomer with a fused-ring polynuclear aromatic compound. The resultant terminally functionalized liquid diene polymers or copolymers can be utilized as dispersants for particulates such as carbon black or graphite and may also be employed as viscosity modifiers for lubricating oils or in electrorheological devices or damping devices.
