Abstract
A functionalized polymer includes a polymer chain and a terminal group linked to the chain through a functionality that contains one or more urethane groups. The functionalized polymer can be provided by reacting a nucleophile with a polymer having terminal iso(thio)cyanate functionality which, in turn, can be provided by reacting a terminally active polymer with a polyiso(thio)cyanate. Even polymers that contain substantial amounts of styrene mer can be used in the described process.
