    摘要: The invention relates to a rubber composition made up of: at least one diene elastomer; 50 to 160 phe (parts by weight per hundred parts by weight of elastomer) of inorganic reinforcement filler; a vulcanisation system; a plasticising system including at least one hydrocarbon resin having a glass transition temperature (Tg) of from -40 °C to 20 °C; as the coupling agent, a hydroxysilane polysulphide having the general formula (I): (HO)
    a R
    (3-a) Si— R'— S
    x — R'— Si R
    (3-b) (OH)
    b where the groups R, which can be the same or different, are hydrocarbon groups preferably comprising 1 to 15 carbon atoms, the groups R', which can be the same or different, are divalent bonding groups preferably comprising 1 to 18 carbon atoms, a and b, which can be the same or different, are equal to 1 or 2, and x is a number no lower than 2; and a primary amine of formula (IV): R-NH
    2 where R is a straight or branched hydrocarbon group including 8 to 24 carbon atoms, said composition being free from or including less than 0.5 phe of guanidine derivative.

    摘要: Rubber composition based on at least one dienic elastomer, a polymeric filler as reinforcing filler, and a coupling agent ensuring bonding between the polymeric filler and the elastomer, said composition being characterized in that said polymeric filler comprises non-aromatic vinyl polymer ('PVNA') nanoparticles carrying a function designated Z and of formula ≡Si-X, where X represents a hydroxyl or hydrolysable group. The PVNA is in particular a copolymer of methyl methacrylate, trimethoxysilylpropyl methacrylate and ethylene glycol dimethacrylate, in the form of nanobeads with a diameter of between 10 and 100 nm. By virtue of a very low density, this polymeric filler allows a reduction in the weight of the compositions of the invention, without deterioration in the reinforcement, and with a substantial reduction in hysteresis. Process for producing such a composition. Masterbatch comprising at least one dienic elastomer and a polymeric filler of this kind, and process for producing such a masterbatch. Use of a rubber composition of this kind for manufacturing rubber articles, more particularly tyres, or for manufacturing semi-finished rubber products intended for said tyres.
