    摘要： This invention relates to a conjugated diene-based rubber composition reinforced with silica-based reinforcement together with a non-silane coupling agent as N-3-(1,2-dihydroxypropyl)-N-oleylammonium bromide and/or N-3-(1,2-dihydroxypropyl)-N-methyl-2-mercaptoimidazolium bromide for endeavoring to both couple synthetic aggregates of precipitated silica to elastomers and enhancing electrical conductivity of such rubber compositions which contain less than 25 parts by weight carbon black per 100 parts by weight elastomer. Said coupling agent materials may be provided for mixing with said diene-based rubber(s), for example, as individual materials, as at least one of said materials being supported on a carbon black carrier or as being pre-reacted, or otherwise pre-treated, with synthetic silica aggregates. The invention includes an article of manufacture, including a tire, having at least one component comprised of such rubber composition.
