FUNCTIONALIZED POLYMER, METHOD FOR PREPARING A FUNCTIONALIZED POLYMER, AND COMPOSITION UNDERSTANDING A FUNCTIONAL POLYMER

摘要

amp;b amp;functionalized polymers. amp;d amp;A functionalized polymer includes a polymer chain and a terminal group connected to the chain through a functionality that contains one or more urethane groups. The functionalized polymer can be provided by reaction of a nucleophile with a polymer having terminal ISO (thio)cyanate functionality to which,In turn,Can be provided by reacting a terminally active polymer with polyiso (thio)cyanate. Even polymers containing substantial quantities of styrene mer can be used in the process described.
