Abstract

A tire component comprising a vulcanized rubber deriving from a functionalized polymer defined by the formula Iwhere π is a polymer chain, B is a boron atom, R1 is a bond or a divalent organic group, and each υ is independently selected from alkoxy groups (—OR), thioalkoxy groups (—SR), amino groups (—NR2), or phosphino groups (—PR2), where each R is independently selected from monovalent organic groups or two R groups form a divalent organic group, which forms a cyclic structure.
