The present invention is directed to a functionalized elastomer comprising the reaction product of a living anionic elastomeric polymer and a polymerization terminator of formula Iwhere n is an integer from 1 to 3;X is a tetravalent organic group selected from a hydrocarbyl group of formula CmH2m-2 where mis an integer from 1 to 10, a group of formula IIwhere R3 is C1 to C10 alkane diyl, and the group of phenyl diyl;R1 and R2 are independently selected from C1 to C10 alkyl, and a group of formula IIIwhere R4, R5 are independently C1 to C10 alkyl, and R6 is C1 to C10 alkanediyl;or R1 and R2 taken together with their common Si atom form a five-membered heterocyclic ring selected from formulas IV and Vwhere R7 is from C1 to C10 alkyl.
