Abstract
The present invention relates to a sulfur-cross-linkable elastomeric composition that is useful for the manufacture of tires. This elastomeric composition is based on at least one isoprene elastomer (in particular natural rubber), a reinforcing inorganic filler (in particular, silica), and an (inorganic filler/isoprene elastomer) coupling agent. The coupling agent is a multifunctional polyorganosiloxane (POS), which comprises functions denoted as 'Y' and 'X', wherein the Y function is at least one hydroxyl or hydrolyzable function grafted to the silicon atoms of the coupling agent and the X function is a group bearing at least one activated ethylene double bond and is grafted to the silicon atoms of the coupling agent. This POS is, in particular, a POS having an imide, acid or ester function, the ethylene double bond of which is activated by at least one adjacent carbonyl group (—C═O). The present invention further relates to a tire comprising the composition described above as well as semi-finished products for tires, in particular, treads, where the tires comprise a rubber composition according to the present invention.
