A functionalized elastomer is disclosed having the formula (P-B n ) q -X, where P is a polydiene segment, B is a styrenic monomer residue, n is the number of styrenic monomer residues, B n is a polystyrenic segment; X is a multifunctional polymerization terminator residue, and q is the number of (P-B n ) chains coupled to X. Also, a method of making a functionalized elastomer is disclosed comprising the steps of: polymerizing a diene based monomer in the presence of an anionic polymerization initiator to produce a polydiene anionic living polymer; further polymerizing the polydiene anionic living polymer with from 1 to 10 equivalents of a styrenic monomer per equivalent of initiator to produce a polydiene-polystyrenic anionic living polymer; and terminating the polydiene-polystyrenic anionic living polymer with a multifunctional terminator.
