    摘要： This invention relates to the preparation of a cis 1,4-polyisoprene rubber-rich rubber composition containing precipitated silica which has been pre-treated with a fatty alcohol and/or epoxidized soybean oil together with an organosilane containing polysulfide coupling agent and to tires having at least one component comprised of such rubber composition. The invention particularly relates to a process of (a) preparing a natural rubber-rich rubber composition comprised of pre-treating precipitated silica aggregates prior to blending with, or in the presence of, dry natural rubber with a fatty alcohol and/or epoxidized soybean oil to the exclusion of sulfur curative for the natural rubber, mixing an organalkoxysiloxane based polysulfide coupling agent with said dry natural rubber coincidentally with or subsequent to said precipitated silica aggregate fatty alcohol and/or epoxidized soybean oil pre-treatment to form a composite thereof, to the exclusion of sulfur curative, followed by (b) mixing the resulting rubber mixture with sulfur curative and (c) curing the resulting rubber composition.

    摘要： This invention relates to the preparation of silica-rich rubber compositions which contain silica reinforcement and silica coupler together with a specified combination of zinc oxide and long chain (fatty) carboxylic acid such as stearic acid. The silica, silica coupling agent, zinc oxide and stearic acid are combined in a manner to form a complex network. The silica is a precipitated silica in a form of silica aggregates which contain hydroxyl groups on its surface. A preferred silica coupling agent is a bis (3-trialkoxysilylalkyl) polysulfide which contains an average of from 2 to about 4, preferably from 2 to about 2.6, connecting sulfur atoms in its polysulfidic bridge. The invention further relates to tires having a component thereof such as, for example, a tread.

    摘要： This invention relates to the preparation of silica-containing rubber compositions which contain precipitated silica reinforcement and use of an oligomeric organomercaptosilane coupling agent containing a plurality of mercapto and silane moieties, and a minimal content, if any, of ethoxy groups and is thus substantially free of ethoxy groups. The interaction of the plurality of mercapto moieties, or groups, of such oligomeric organomercaptosilane with the diene-based elastomer can promote a significant viscosity build up of the uncured rubber composition in a preliminary non-productive mixing stage and therefore present significant rubber processing difficulties during the mixing of the rubber composition. A challenge is therefore presented for reducing such viscosity buildup for such uncured silica-containing rubber composition.

    摘要： The process and catalyst system of this invention can be utilized to synthesize a highly random styrene-butadiene rubber having a high trans content by solution polymerization. The styrene-butadiene rubber made by the process of this invention can be utilized in tire tread rubbers that exhibit improved wear characteristics. This invention more specifically reveals a catalyst system for use in isothermal polymerizations which consists essentially of (a) an organolithium compound, (b) a calcium alkoxide and (c) a lithium alkoxide. The subject invention further discloses a process for synthesizing a random styrene-butadiene rubber having a low vinyl content by a process which comprises copolymerizing styrene and 1,3-butadiene under isothermal conditions in an organic solvent in the presence of a catalyst system which consists essentially of (a) an organolithium compound, (b) a calcium alkoxide and (c) a lithium alkoxide. An amine can also be added to the catalyst system to increase the molecular weight (Mooney viscosity) of the rubber.
