    • 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.
    • 本发明涉及含有沉淀二氧化硅的顺式1,4-聚异戊二烯橡胶丰富橡胶组合物的制备,该组合物已经用脂肪醇和/或环氧化大豆油与含有机硅烷的多硫化物偶联剂预处理,并且具有 至少一种由这种橡胶组合物组成的组分。 本发明特别涉及(a)制备富含天然橡胶的橡胶组合物的方法,所述橡胶组合物在与天然橡胶与脂肪醇和/或环氧化大豆混合之前或在干燥天然橡胶存在下预处理沉淀二氧化硅骨料 油,以排除天然橡胶的硫固化剂,将所述有机烷氧基硅氧烷基多硫化物偶联剂与所述干燥天然橡胶在所述沉淀二氧化硅骨料脂肪醇和/或环氧化大豆油预处理中或之后巧合地混合以形成其复合物, 排除硫固化剂,然后(b)将所得橡胶混合物与硫固化剂混合,和(c)固化所得橡胶组合物。
