    摘要: A method is presented for making alkoxy-modified silsesquioxanes (AMS) or co-alkoxy-modified silsesquioxanes (co-AMS,) comprising the steps of (a) combining as a reaction mixture (i) water, (ii) an acid-stable solvent for the water, (iii) a solid strong cationic hydrolysis and condensation catalyst, and (iv) a trialkoxysilane compound, (b) allowing the reaction mixture to react for about 0.5 hours to about 200 hours to form the alkoxy-modified silsesquioxanes; and (c) recovering the alkoxy-modified silsesquioxanes from the reaction mixture. The use of solid strong cationic catalysts in this reaction system is advantageous because they remain as solids throughout the reaction, allowing simplified separation of the solid catalyst from the soluble AMS or co-AMS products, resulting in total or near total recovery of the AMS or co-AMS products, the products being free of, or substantially free of residual acid catalyst, as well as virtual total recovery of the catalyst for recycling. The improved AMS and co-AMS compounds, vulcanizable rubber compounds containing them, and a pneumatic tire having a component made from the vulcanized rubber compounds are also presented.

    摘要: A method is presented for making an amino alkoxy-modified silsesquioxane (amino AMS) comprising one or more compounds selected from the group consisting of an amino-AMS, an amino/mercaptan co-AMS, an amino/blocked mercaptan co-AMS, and mixtures of these. The use of solid strong cationic catalysts in this reaction system is advantageous because the catalyst remains as a solid throughout the reaction, allowing simplified separation of the solid catalyst from the soluble amino AMS or amino co-AMS products, resulting in total or near total recovery of the amino AMS or amino co-AMS products, as well as virtual total recovery of the catalyst for recycling. The use of the solid strong cationic catalysts is advantageous because it results in amino AMS products that are free of, or substantially free of, residual acid catalyst.

    摘要: The present invention provides silica-filled, vulcanized elastomeric compounds comprising an elastomer mixed with at least a silica filler, a processing aid, and a curing agent, and processes for the preparation of the same. Generally, the present invention provides processing aids which effectively reduce or replace the amount (i.e., about 10 percent by weight based upon the silica filler) of the processing aid bis[3-triethyoxysilyl)propyl]tetrasulfide (“Si69”) used in the production of silica-filled rubber stocks. These new processing aids include alkyl alkoxysilanes, fatty acid esters of hydrogenated and non-hydrogenated sugars and the polyoxyethylene derivatives thereof, and combinations thereof, with or without various non-reinforcing fillers such as mineral fillers. The processing aids do not hinder the physical properties of the compounds and have been found to be excellent substitutes for Si69. The processing aids may be supported on the silica filler or any of the other fillers employed in the composition for improved handling, safety and performance. Processes for the preparation of the silica filled vulcanizable elastomers are provided as well as pneumatic tires employing tread stock comprising the novel vulcanizable elastomers.
