Abstract
The subject invention reveals 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. It further reveals a tire having a tread that is made from such a silica/rubber blend.
