  • Functionalized polymers and improved vulcanizates therefrom
    Publication number: 20060074197
    Abstract: A functionalized polymer defined by the formula ?-R1-?, where ? is a polymer chain, R1 is a bond or a divalent organic group, and ? is a sulfur-containing heterocycle.
    Type: Application

  • Use of sulfur containing initiators for anionic polymerization of monomers
    Publication number: 20060030657
    Abstract: 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.
