    摘要： 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.

    摘要： Polymer-filler coupling compounds with the formula B-A-S x -N are claimed. In these compounds, B is an azaheterocyclic oxygen or sulfur containing moiety, or an allyltin moiety; S x is a polysulfide, where x is between 2 and about 10; A is a linking atom or group that forms a bridge between B and S x ; and N is a blocking group. S x can be a disulfide. N can be a conventional blocking group or other group such as -A-B. Methods for using the polymer-filler coupling compounds to modify polymers containing unsaturated carbon-carbon bonds and promote filler dispersion are also claimed. Additionally, vulcanizable rubber compositions containing the polymer-filler coupling compounds and methods for making vulcanized rubber compositions using the polymer-filler coupling compounds are also claimed.

    摘要： Novel solid supported anionic polymerization initiators that are multiply metalated with Group IA alkali metal atoms are provided and employed to produce extremely high molecular weight branched diene polymers. The initiators are prepared by metalating a particle comprising a thermoplastic polymer or a cured elastomer in the presence of a polar coordinator. The polymers obtained by anionic polymerization employing the initiators are multiply branched, with a polymer chain covalently attached to the particle at virtually every metalation site. The macro-branched polymers exhibit desirable properties, such as an extremely high molecular weight, a controlled molecular weight distribution, T g and vinyl content, and the ability to readily absorb hydrocarbon solvents and oils. The polymers are easily compounded to form vulcanizable elastomeric compounds and articles that have excellent resistance to wear and tear and exhibit reduced hysteresis properties.
