    摘要: The present invention relates to a technique to efficiently and effectively disperse silica throughout a rubbery polymer. By utilizing this technique mechanical mixing procedures that are energy intensive and require large capital investments in mixing equipment can be significantly reduced. By reducing the amount of shearing forces to which the rubber is subjected polymer degradation is also significantly reduced. The utilization of the technique of this invention also results in a uniform blend of the silica throughout the rubber and consequently better interaction between the silica and the rubber. This results in better physical properties, such as higher modulus. The subject invention more specifically discloses a process for preparing a silica/rubber blend which comprises dispersing silica, a silica coupling agent, and a low molecular weight end-group functionalized diene rubber throughout a cement of a conventional rubbery polymer, and subsequently recovering the silica/rubber blend from the organic solvent. The present invention further reveals a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidewalls extending radially from and connecting said tread to said beads, wherein said tread is adapted to be ground-contacting, and wherein said tread is comprised of the silica/rubber blend made by dispersing silica, a silica coupling agent, and a low molecular weight end-group functionalized diene rubber throughout a cement of a conventional rubbery polymer, and subsequently recovering the silica/rubber blend from the organic solvent.
