ABSTRACT:
The invention provides an elastomeric composition based on at least an isoprene elastomer, a reinforcing inorganic filler and, as (inorganic filler/isoprene elastomer) coupling agent, a citraconimido-alkoxysilane, in particular an N-[((C1-C3)alkyl-(C1-C3)alkoxysilyl)]-citraconimide. The isoprene elastomer is in particular natural rubber and the reinforcing inorganic filler a siliceous or aluminous filler of the highly dispersible type. Also provided is a process for preparing such a composition. The use of this composition for the manufacture of tires or semi-finished products for tires, in particular treads for heavy-vehicle tires, is also provided.
