The present invention is directed to a catalyst system for synthesizing rubbery polymers, such as polybutadiene rubber, styrene-butadiene rubber, isoprene-butadiene rubber, or styrene-isoprene-butadiene rubber, that are amine functionalized and have a high trans or high vinyl microstructure. The catalyst system, in one embodiment, includes an organolithium amine compound, and one or more of (a) a group IIa metal salt of an amino glycol or a glycol ether, (b) an organoaluminum compound, or (c) an amine compound. The amine functionalized rubbery polymers can be utilized in tire tread rubbers where the rubbery polymers may provide desirable wear properties without substantially sacrificing other performance characteristic(s), e.g., traction properties.

What is claimed is: 1. A catalyst system comprising: an organolithium amine compound defined by A-(CH2)n-Li, wherein R′, together with the adjacent nitrogen, defines (1) a heterocyclic aromatic amine group having 2 to 18 ring carbon atoms or (2) a heterocyclic non-aromatic amine group having
What is claimed is: 1. A catalyst system comprising: an organolithium amine compound defined by A-(CH2)n-Li, wherein R′, together with the adjacent nitrogen, defines (1) a heterocyclic aromatic amine group having 2 to 18 ring carbon atoms or (2) a heterocyclic non-aromatic amine group having 2 to 18 ring carbon atoms, wherein A is a phenyl group, and wherein n is 1 to 20; and one or more of (a) a group IIa metal salt of an amino glycol or a glycol ether, (b) an organoaluminum compound, or (c) an amine compound. 2. The catalyst system of claim 1 wherein R′ defines the heterocyclic aromatic amine group having 2 to 18 ring carbon atoms. 3. The catalyst system of claim 1 wherein R′ defines the heterocyclic non-aromatic amine group having 2 to 18 ring carbon atoms. 4. The catalyst system of claim 3 wherein the heterocyclic non-aromatic amine group is a 5-, 6-, or 7-membered ring structure with one or more nitrogen atoms as part of the ring. 5. The catalyst system of claim 4 wherein the heterocyclic non-aromatic amine group is pyrrolidine, piperidine, or hexamethylene imine and n is 2, or 4. 6. A method comprising: polymerizing one or more different types of conjugated diene monomers and optionally vinyl aromatic monomers in the presence of a catalyst system for synthesizing rubbery polymers that are amine functionalized comprising: an organolithium amine compound defined by R′N-A-(CH2)n-Li, wherein R′, together with the adjacent nitrogen, defines (1) a heterocyclic aromatic amine group having 2 to 18 ring carbon atoms or (2) a heterocyclic non-aromatic amine group having 2 to 18 ring carbon atoms, wherein A is a phenyl group, and wherein n is 1 to 20; and one or more of (a) a group IIa metal salt of an amino glycol or a glycol ether, (b) an organoaluminum compound, or (c) an amine compound. 7. The method of claim 6 wherein polymerizing the conjugated diolefin monomer in the presence of the catalyst system includes polymerizing the vinyl aromatic monomer with the one or more different types of conjugated diolefin monomers, and wherein the vinyl aromatic monomer is styrene and the one or more different types of conjugated diolefin monomers is butadiene or butadiene and isoprene for synthesizing styrene-butadiene rubber or styrene-isoprene butadiene that is amine functionalized. 8. The method of claim 6 wherein polymerizing the conjugated diolefin monomer in the presence of the catalyst system includes polymerizing the one or more different types of conjugated diolefin monomers, and wherein the one or more different types of conjugated diolefin monomers is butadiene or butadiene and isoprene for synthesizing polybutadiene rubber or isoprene-butadiene rubber that is amine functionalized. 9. A tire comprising: a rubber compound including a rubbery polymer resulting from the method comprising polymerizing one or more different types of conjugated diene monomers and optionally vinyl aromatic monomers in the presence of a catalyst system for synthesizing rubbery polymers that are amine functionalized comprising: an organolithium amine compound defined by R′N-A-(CH2)n—Li, wherein R′, together with the adjacent nitrogen, defines (1) a heterocyclic aromatic amine group having 2 to 18 ring carbon atoms or (2) a heterocyclic non-aromatic amine group having 2 to 18 ring carbon atoms, wherein A is a phenyl group, and wherein n is 1 to 20; and one or more of (a) a group IIa metal salt of an amino glycol or a glycol ether, (b) an organoaluminum compound, or (c) an amine compound. 10. The tire of claim 9 wherein the rubber compound further comprises silica filler, carbon black filler, or mixtures thereof.
