Abstract

A functionalized polymer includes a polymer chain and, bonded thereto, a functional group having the general formula —NQOR1 where R1 is a hydrogen atom or —CH2Z where Z is a hydrogen atom or a substituted or unsubstituted aryl, alkyl, alkenyl, alkenaryl, aralkenyl, alkaryl, or aralkyl group and where Q is a moiety connected to the nitrogen atom of the functional group through a C, N, O, or S atom. The material can be the reaction product of a living polymer and a compound that includes nitroso functionality. The functional group can interact with particulate filler such as, e.g., carbon black.
