A functionalized polymer prepared by a process comprising the steps of preparing a pseudo-living polymer by polymerizing conjugated monomer with a lanthanide-based catalyst, and reacting the pseudo-living polymer with a functionalizing agent defined by the formula (I) <?in-line-formulae description="In-line Formulae" end="lead"?>A-R<SUP>1</SUP>-Z (I) <?in-line-formulae description="In-line Formulae" end="tail"?> where R<SUP>1 </SUP>is a divalent bond or divalent organic group comprising from 0 to about 20 carbon atoms, A is a substituent that will undergo an addition reaction with a pseudo-living polymer, and Z is a substituent that will react or interact with silica or carbon black reinforcing fillers, with the proviso that A, R<SUP>1</SUP>, and Z are substituents that will not protonate a pseudo-living polymer.
