    摘要： The invention relates to a rubber composition devoid of or practically devoid of zinc or zinc derivative, usable in particular for the manufacture of tires or tire treads, comprising at least: a diene elastomer; an inorganic filler as reinforcing filler; optionally carbon black, in an amount less than 5 phr; a silane polysulfide of formula (I): in which: the symbols R1 and R2, which may be identical or different, each represent a monovalent hydrocarbon group selected from among alkyls, whether straight-chain or branched, having from 1 to 6 carbon atoms and the phenyl radical; the symbols R3, which may be identical or different, each represent hydrogen or a monovalent hydrocarbon group selected from among alkyls, whether straight-chain or branched, having from 1 to 4 carbon atoms and alkoxyalkyls, whether straight-chain or branched, having from 2 to 8 carbon atoms; the symbols Z, which may be identical or different, are divalent bond groups comprising from 1 to 18 carbon atoms; x is an integer or fractional number equal to or greater than 2.

    摘要： Tire tread comprising a rubber composition based on at least a diene elastomer, a nonblack reinforcing filler, in particular inorganic filler, and a coupling agent providing the bonding between the diene elastomer and said filler, said composition being characterized in that it additionally comprises a prophoto-oxidizing agent and optionally carbon black at a level of less than 5 phr (parts by weight per hundred parts of elastomer). The prophoto-oxidizing agent is in particular a photo-initiator of radical or cationic type, which may or may not be activated by the presence of a photosensitizer.The tires comprising such a tread exhibit, after photo-oxidation (exposure to UV-visible radiation) of said tread, a significant increase in the grip on a wet road.

    摘要： A tire tread comprising a rubber composition based on at least a diene elastomer, a reinforcing inorganic filler such as silica, an inorganic filler/elastomer coupling agent and carbon black in a very small quantity, in an amount of between 0.05 and 2.0 phr. The tires comprising such a tread have, after photo-oxidation treatment of the latter, a significantly improved grip on wet roads. Such photo-oxidising treatment, in particular under visible UV radiation, may advantageously be performed during the manufacture of the treads or tires itself, in the uncured state or after vulcanisation, or even later on in the life of said tires.
