<p>A functionalized polymer includes a directly bonded moiety, which can be located at a terminus of the polymer, defined by the formula -NH-NR<Sup>1</Sup>R<Sup>2</Sup> where R<Sup>1</Sup> and R<Sup>2</Sup> independently are substituted or unsubstituted alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, allyl, aralkyl, alkaryl, or alkynyl groups, or together form a substituted or unsubstituted alkylene, alkenylene, cycloalkylene, cycloalkenylene, or arylene group. The functionalized polymer can be provided by reacting a living polymer with a hydrazone. Such polymers can be used in the production of compositions that include particulate fillers.</p> |
