The invention relates to propylene articulated polysulphide monoorganoxysilanes of formula (I); wherein R?1¿, R?2¿ et R?3¿ are monovalent hydrocarbon groups and x is a number ranging from 3 .plusmn. 0,1 to 5 .plusmn. 0,1. Said compounds can be used as white charge-elastomer coupling agents in dienic rubber compositions comprising a white charge such as a siliceous material as a reinforcing charge. The invention also relates to dienic elastomer compositions comprising at least one polysulphide silane of formula (I), and dienic elastomer articles prepared from said compositions.
La présente invention concerne des monoorganoxysilanes polysulfurés à rotule propylène de formule (I); dans laquelle les symboles R1, R2 et R3 sont des groupes hydrocarbonés monovalents et x est un nombre allant de 3 .plusmn. 0,1 à 5 .plusmn. 0,1. Ces composés sont utilisables comme agent de couplage charge blanche-élastomère dans les compositions de caoutchoucs diéniques comprenant, à titre de charge renforçante, une charge blanche telle qu'une matière siliceuse. L'invention concerne par ailleurs les compositions d'élastomères diéniques comprenant au moins un silane polysulfuré de formule (I), ainsi que les articles en élastomère(s) diénique(s) préparés à partir de telles compositions.
