Abstract (en)
[origin: WO2013087693A1] The invention relates to a rubber composition that is free of zinc or that contains less than 0.5 parts per hundred parts of elastomer, phr, of zinc, and that is free of guanidine derivatives or contains less than 0.5 phr of guanidine derivatives, based on at least a diene elastomer, an inorganic filler as reinforcing filler, a blocked mercaptosilane corresponding to the general formula (I): in which: -the R1 symbols, which are identical or different, each represent a monovalent hydrocarbon-based group chosen from alkyls, which are linear or branched, cycloalkyls or aryls, having from 1 to 18 carbon atoms; -the R2 symbols, which are identical or different, each represent hydrogen or a monovalent hydrocarbon-based group chosen from alkyls, which are linear or branched, cycloalkyls or aryls, having from 1 to 18 carbon atoms; -the A symbol represents hydrogen or a monovalent hydrocarbon-based group chosen from alkyls, which are linear or branched, cycloalkyls or aryls, having from 1 to 18 carbon atoms and alkoxyalkyls, which are linear or branched, having from 2 to 8 carbon atoms; -the Z symbol represents a divalent bonding group comprising from 1 to 18 carbon atoms; -a is an integer equal to 1, 2 or 3.
