A functionalized polymer includes a directly bonded moiety, which can be located at a terminus of the polymer, defined by the formula —NH—NR1R2 where R1 and R2 independently are substituted or unsubstituted alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, allyl, aralkyl, alkaryl, or alkynyl groups, o

A functionalized polymer includes a directly bonded moiety, which can be located at a terminus of the polymer, defined by the formula —NH—NR1R2 where R1 and R2 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.
