    摘要： Disclosed herein are a modified high cis polydiene polymer, processes for preparing the modified high cis polydiene polymer, and tire rubber compositions containing the modified high cis polydiene polymer. The processes make use of a functionalizing compound of formula I or formula II and a coupling agent to prepare the modified high cis polydiene polymer from a quantity of conjugated diene monomer polymerized using a lanthanide-based catalyst system. The modified high cis polydiene polymer includes at least one polymer chain having a residue from the functionalizing compound and a residue from the coupling agent and can be utilized in tire rubber compositions in combination with other ingredients such as fillers.

    摘要： A functionalized polymer includes the reaction product of a reactive polymer and a compound that includes an aryl group having at least one directly bonded OGp substituent, where Gp is a protecting group, and a substituent (Q) which is free of active hydrogen atoms and which is, or connects to the aryl group through, a moiety that includes a carbon-to-nitrogen multiple bond. The polymer can be provided from a solution that includes one or more types of ethylenically unsaturated monomers which include at least one type of polyene, particularly one or more conjugated dienes in certain embodiments. An active terminus of the resulting reactive polymer can react with the Q substituent of the compound so as to provide a polymer having as a terminal functionality the radical of a compound that includes an aryl group having at least one directly bonded OGp substituent.
