PROBLEM TO BE SOLVED: To provide a functionalized polymer which includes a directly bonded hydrazone radical, which can be located at a terminus of the polymer. SOLUTION: The functionalized polymer includes a directly bonded moiety, which can be located at a terminus of the polymer, defined by the formula -NH-NR<SP>1</SP>R<SP>2</SP>wherein R<SP>1</SP>and R<SP>2</SP>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.
