Patent number: 7351759Abstract: An elastomeric composition usable for the manufacture of tires, based on at least (i) a diene elastomer, (ii) an inorganic filler as reinforcing filler and (iii), as (inorganic filler/diene elastomer) coupling agent, a polysilylated organosilicon compound which is at least bifunctional and can be grafted onto the elastomer by means of a sulfur group having a polythiosulfenamide function, of formula: ?Si—A—Sx—NR1R2 ,??(I) in which: A is a divalent bond group, whether straight-chain or branched, which makes it possible to join the polythiosulfenamide group to a first silicon atom of the organosilicon compound; x is an integer or fractional number of from 2 to 4; R1 represents hydrogen, a monovalent hydrocarbon group, or R2; and R2 represents the grouping: —B—Si?, in which: B is a divalent bond group, whether straight-chain or branched; Si represents a second silicon atom of the organosilicon compound. The invention also concerns tires and tire treads comprising a composition of this type.Type: GrantFiled: December 11, 2003Date of Patent: April 1, 2008Assignee: Michelin Recherche et Technique S.A.Inventors: José-Carlos Araujo-Da-Silva, Christiane Blanchard, Gérard Mignani, Salvatore Pagano, Jean-Claude Tardivat

Publication number: 20080039562Abstract: The disclosure herein relates to organofunctional silanes and mixtures of organofunctional silanes possessing mercaptan and hydrocarbyl and/or heterocarbyl functionality. These silanes reduce or eliminate the generation of volatile organic compounds (VOC's) during use, aid in the processing of filled elastomeric materials and enhance the end-use properties of the filled elastomer. The present disclosure relates to a rubber composition and article comprising these silanes.Type: ApplicationFiled: August 14, 2006Publication date: February 14, 2008Applicant: General Electric CompanyInventors: Antonio Chaves, Eric R. Pohl, Christopher M. Hartshorn

Publication number: 20080027162Abstract: 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.Type: ApplicationFiled: July 25, 2006Publication date: January 31, 2008Inventors: Kuo-Chih Hua, Shingo Futamura, Wen-Liang Hsu, Paul Harry Sandstrom
