Abstract (en)
[origin: WO0196442A1] The invention concerns a sulphur crosslinkable elastomer composition, for use in the manufacture of tyres, comprising at least: i) an isoprene elastomer, in particular natural rubber; ii) a reinforcing inorganic filler, in particular silica; and iii) as coupling agent (white filler/isoprene elastomer), a multifunctional polyorganosiloxane (POS) comprising, grafted on its silicone atoms, part at least of a hydroxyl or hydrolysable function, at least a group bearing at least an activated double ethylene bond. Said POS is in particular a POS with imide, acid or ester function, whereof the double ethylene bond is activated by at least an adjacent carbonyl group (>C=O). The invention also concerns a tyre or semi-finished product, in particular a running tread for tyre comprising said inventive composition.
