  • Patent number: 9505917
    Abstract: A tire, the inner liner of which comprises a rubber composition based on at least predominantly a highly unsaturated diene elastomer, a reinforcing organic filler, graphite, chalk, a plasticizing hydrocarbon resin, the glass transition temperature, Tg, of which is greater than 20° C. and the softening point of which is less than 170° C. The use of such a composition in the inner liner of the tire, including graphite and a non-reinforcing filler of chalk type, makes it possible to notably improve the airtightness properties with respect to a control composition which comprises only graphite and which already performs very well in this aspect, but also with respect to a control composition conventionally used in the inner liners of tires, while maintaining a good level of the stiffness and processability properties as the conventional control compositions.

  • Publication number: 20130030097
    Abstract: This invention relates to an article, in particular a pneumatic tire for a vehicle, comprising at least one external rubber mixture, in particular a tread, said external mixture comprising a rubber mixture consisting of at least one diene elastomer such as BR, SBR or NR, a reinforcing filler such as silica, a crosslinking system such as a vulcanization system, between 0.2 and 10 pce of an antioxidant, for example a substituted paraphenylenediamine, and between 0.2 and 10 pce of a lanthanide acetylacetonate such as a neodymium actylacetonate. The latter makes it possible to advantageously reduce the consumption of antioxidant during the thermal oxidizing aging of the composition and hence of the external mixture.

  • Patent number: 7470743
    Abstract: A crosslinkable or crosslinked rubber composition is described which includes a diene elastomer having a mass content of cyclic vinyl units of greater than 15%, and which may be used to form a tire tread. Also described is a tire tread and a tire incorporating the tread. The composition contains a linear or branched diene elastomer derived from at least one conjugated diene, and a reinforcing filler. The elastomer has cyclic vinyl units according to a mass content of greater than or equal to 15% and a number-average molecular weight of from 30,000 to 350,000 g/mol. The elastomer may be obtained by anionic polymerization of one or more monomers including a conjugated diene in an inert hydrocarbon solvent with a catalytic system including an organolithium initiator and a polar agent with several heteroatoms. The reaction may be performed batchwise where the polar agent:initiator molar ratio is greater than 8, or continuously where the polar agent:initiator molar ratio is greater than or equal to 3.
