Abstract:
A rubber composition based at least on a reinforcing filler, on a Lewis or Bronsted acid, on a diene elastomer obtained by stereospecific polymerization in the presence of a neodymium-based Ziegler-Natta catalytic system and on a 1,3-dipolar compound comprising an associative group, is provided. The Lewis acid is selected from the group consisting of aluminium oxides, titanium oxides and the compounds M(L) n , with M being boron, magnesium, aluminium, titanium, iron, zinc, indium or ytterbium, L being a monodentate or bidendate ligand and n being an integer ranging from 2 to 4. The Bronsted acid is selected from the group consisting of sulfonic acids. Such a composition exhibits a very low hysteresis.

Claim (Index 17):
A rubber composition according to  claim 1 , in which the acid is a Lewis acid.
