Abstract
The present invention relates to new elastomeric materials for the production of tyres for vehicle wheels with good mechanical properties, in particular high moduli associated with low hysteresis values, including new reinforcement materials. Said reinforcement materials are obtainable by derivatising silica—in-situ during the mixing of the elastomeric composition, or previously—with special silanising agents (A) and silsesquioxanes (B), both substituted with reactive alkenyl functionalities.
