RUBBER COMPOSITION INCLUDING AN ORGANOSILANE COUPLING AGENT

摘要

The invention relates to a rubber composition which can be used for manufacturing tyres, consisting of at least: one diene elastomer; a sulphur cross-linking system; an inorganic filler serving as a reinforcing filler; a coupling agent with the following general formula I: (HO)3-n R1 n Si - Z - Sm - R2, where: R1, identical or different, are each a monovalent hydrocarbon group selected from among linear or branched alkyls, cycloalkyls or aryls, having 1 to 18 carbon atoms; R2 is a monovalent hydrocarbon group selected from among linear or branched alkyls, cycloalkyls or aryls, having 1 to 30 carbon atoms; Z is a divalent bonding group comprising 1 to 18 carbon atoms; n is an integer equal to 0, 1 or 2; and m is a number greater than or equal to 2.
