    • The present invention discloses novel hydrocarbon core polysulfide silanes and methods of preparing the hydrocarbon core polysulfide silanes. Preferably, the silanes of the present invention contain assemblies of a single unit of a hydrolyzable silane group, tethered to one end of a chain of sulfur atoms, and several of these assemblies are bound to a common central hydrophobic core via the other end of the sulfur atoms chain. The hydrocarbon core polysulfide silanes may be incorporated into filled elastomeric compositions providing improved dispersiblity of the filler materials. Mineral fillers may be pre-treated with the hydrocarbon core polysulfide silanes prior to use in elastomeric compositions.
    • 本发明公开了新型烃核聚硫硅烷及其制备方法。 优选地,本发明的硅烷含有与水解性硅烷基团的单一单元的组合,其结合到硫原子链的一端,并且这些组合中的几个通过另一端结合到共同的中心疏水性核心 硫原子链。 烃核心多硫化硅烷可以加入到填充的弹性体组合物中,从而提供填料材料的改进的分散性。 矿物填料可以在用于弹性体组合物之前用烃核心多硫化硅烷预处理。
