    摘要: Triorgano substituted-tin lithium initiators are made in a dimethyl ether solvent. The substitution of dimethyl ether as the solvent for the traditional tetrahydrofuran solvent results in an initiator for anionic polymerizations that can produce less 1,2-vinyl repeat units. The dimethyl ether is also easier to remove from the polymerization media because it has a boiling point at one atmosphere of minus 24.8.degree. C. and thus is a gas at 25.degree. C.

    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 invention provides vulcanizable rubber compound having improved tensile mechanical and dynamic viscoelastic properties. The compounds are formed by mixing an elastomer, containing unsaturated carbon-carbon bonds in its molecular structure, with a reinforcing inorganic filler silica in the presence of an alkyl alkoxysilane and a non-sulfur coupling agent that binds to the rubber backbone with an “ene” linkage or a 1,3 dipolar addition linkage. In particular, the coupling agent and the alkyl alkoxysilane are present in the compound in a weight ratio of about 0.0001:1 to about 1:1.

    摘要: Amino alkoxy-modified silsesquioxanes (amino AMS), and/or amino co-AMS compounds that also comprise a mercaptosilane or a blocked mercaptosilane, are excellent adhesives for coating plated or unplated metal wire for adherence of the wire to a rubber stock. The amino AMS and/or the amino/mercaptan co-AMS adhesives can be used with all types of rubber and there is no requirement for the use of special adhesive additives to the rubber vulcanizates, such as, but not limited to, cobalt, resins and high sulfur levels. In particular, the use of amino AMS and/or amino/mercaptan co-AMS compounds as adhesives for bonding wire to rubber also improves the adherence performance of the reinforcements to obtain sufficient bonding that is resistant to degradation over the course of time, especially resistance to thermal aging and/or thermo-oxidizing aging, in particular corrosion in the presence of water. Vulcanized rubber compositions that contain an amino AMS and/or amino/mercaptan co-AMS compound also have improved adhesion to embedded uncoated steel after humidity aging compared with vulcanized rubber compositions not containing the amino alkoxy-modified silsesquioxane.

    摘要: A vulcanizable rubber composition is presented that comprises an elastomer; a reinforcing filler selected from silica, carbon black, and mixtures thereof, a cure agent; and an amino alkoxy-modified silsesquioxane (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, mixtures thereof, and weak acid-neutralized solid and aqueous solutions thereof. Addition of such compounds to the rubber composition provides improved dynamic viscoelastic and mechanical properties of the vulcanized rubber compound and predict that tire components, especially tread stocks, will provide tires having improved snow traction, lower rolling resistance but equal wet traction, increased rebound, decreased hysteresis, and a general improvement in tire performance.
