    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, Tg 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.

    摘要： Methods are provided for making solution masterbatches containing a diene elastomer in an organic solvent and a silica filler, having a first average particle size, that is ground in an organic solvent to form a silica having a reduced second average particle size. Grinding of the silica in the organic solvent, with or without other ingredients including the elastomer, produces a solution masterbatch in which the silica is mixed with and well dispersed in the elastomer. The use of such desolventized solution masterbatches in vulcanizable rubber compounds results in excellent processing characteristics allowing for the reduced use of processing aids such as oil. The compound also demonstrates improved properties, including reduced hysteresis.
