  An initiator is presented for anionically polymerizing monomers, to provide a functional head group on the polymer. A polymer having a functional head group derived from a sulfur containing anionic initiator, and optionally as additional functional group resulting from the use of a functional terminating reagent, coupling agent or linking agent is also provided. A method is presented for anionically polymerizing monomers comprising the step of polymerizing the monomers with a sulfur containing anionic initiator to provide a functional head group on the polymer. An elastomeric compound, comprising a functional polymer and filler is also described. Also provided is a tire having decreased rolling resistance resulting from a tire component containing a vulcanizable elastomeric compound.
