Abstract
Rubber composition based on at least one diene elastomer, a polymer filler as reinforcing filler, a coupling agent providing the bond between the polymer filler and the elastomer. The polymer filler comprises nanoparticles of non-aromatic vinnyl polymer (“NAVP”) bearing a function Z of formula ≡Si—X, X representing a hydroxyl or hydrolysable group. The NAVP is in particular a copolymer of methyl methacrylate, trimethoxysilylpropyl methacrylate and ethylene glycol dimethacrylate, in the form of nanobeads the diameter of which is between 10 and 100 nm.
