<p>The invention concerns organosilicon compounds selected in particular among polyfunctional silanes bearing each a polythiosulphenamide group of formula: R1 Sx NR2R3, wherein: R1, x, R2 and R3 are such as defined in Claim 1. Said compounds are useful as white filler-elastomer coupling agents in diene rubber compositions comprising, as reinforcing filler, a white filler such as a siliceous material. The invention also concerns diene elastomer compositions comprising at least an organosilicon compound bearing a radical with dithiosulphenamide function of formula (I), as well as diene elastomer articles based on said compositions.</p> |
