摘要

An elastomeric composition, processes for preparing an elastomeric composition and for attaching a load inorganic and a elastu00c8mero diu00eanico in an elastomeric composition.The use of a rubber composition and a organossilano polifuncional, pneumatic, semifinished product for tyre and tread of tyre ".An elastomeric composition based on at least one diu00eanico elastomer, an inorganic load as load which reinforces.A organossilano polifuncional as coupling agent (load inorganic / elastomer diu00eanico), with at least two functions indicated "X" and "Y" enxertu00e1vel, on the one hand,On the elastomer by means of function x, and on the other hand, on the load by means of inorganic function y, characterized by the fact that this function y is a function hidroxissilila ( sym Si oh).Preferably, this organossilano is a polissulfeto of hidroxissilano and the elastomer diu00eanico is selected in the group consisting of natural rubber, butadienos,The poliisoprenos synthesis, copolymers of butadiene, isoprene copolymers, and the load is a load silicosa inorganic which reinforces or aluminous type highly dispersible.Tyres or semi-finished products for tyres, in particular tread of tyres, comprising a composition according to the invention.
