Functionalized polymers and improved tires therefrom

摘要

A functionalized elastomer defined by the formula where pi includes a polymer chain, theta includes a group 14 element, R¹ and R² each independently include hydrogen, a monovalent organic group, or a polymer chain, R³ and R⁴ each independently include a divalent organic group or a covalent bond, R⁵, R⁶, R⁷, R⁸ and R⁹ each independently include a monovalent organic group or a hydrogen atom.
