摘要：
The invention relates to a rubber composition free of zinc or containing less than 0.5 pce of zinc, which can be used for manufacturing tyres, made of at least: a dienic elastomer; a sulphur-based cross-linking system; an inorganic filler as a reinforcing filler; a blocked mercaptosilane with the following general formula (I): (R
3 O) R
2 R
1 -Si - Z- S -C (=O) - A, where: R
1 and R
2 , identical or different, are a monovalent hydrocarbon group selected from among linear or branched alkyls, cycloalkyls or aryls, having 1 to 18 carbon atoms; R
3 is a monovalent hydrocarbon group selected from among linear or branched alkyls, having 1 to 4 carbon atoms; A is hydrogen or a monovalent hydrocarbon group selected from among linear or branched alkyls, cycloalkyls or aryls, having 1 to 18 carbon atoms; and Z is a divalent bonding group comprising 1 to 18 carbon atoms.
