摘要: A method for preparing a functionalized polymer comprising the steps of pseudo-living by polymerizing conjugated diene monomer with lanthanide-based catalyst, and reacting at least one functionalizing agent defined formula (I) where is substituent that will undergo an addition reaction polymer, R1 divalent organic group, R2 monovalent each R4, which may be same or different, group -OR5 R5 proviso A, R?1, R2, R5? are substituents not protonate polymer. Also, vulcanizable composition containing
