"Elastomeric composition usable for the manufacture of tyres, process to prepare a vulcanisable rubber composition and to copulate with a load and a elastu00c8mero inorganic isopru00eanico,Uses of a rubber compound and a multifunctional poliorganossiloxano, pneumatic and semifinished product for tyre ".An elastomeric composition, reticulu00e1vel with sulphur, usable for the manufacture of tyres, comprising at least: (I) an elastomer isopru00eanico,Mainly natural rubber; (II) a load inorganic reinforcement, mainly of silica; and (III) as an agent of copulation (white cargo / elastomer isopru00eanico)A poliorganossiloxano (POS) multifunctional comprising grafted on silicon atoms, on one side, at least one hydroxyl or hydrolysable function, on the other hand,At least one group with at least one double bond etilu00eanica activated.This POS is notably a POS with imide acid or ester function, which etilu00eanica double bond is activated by at least one carbonyl group (C = O) adjacent.Pneumatic or semifinished product, notably the tread for tyre comprising a rubber composition according to the invention.
