  • Rubber composition for running tread and method for obtaining same
    Patent number: 7649042
    Abstract: The present invention relates to a rubber composition usable for constituting a tire tread, said composition being based on at least (i) a reinforcing inorganic filler, (ii) a diene elastomer having a molar ratio of units originating from conjugated dienes which is greater than 30% which is prepared in emulsion and comprises carboxylic acid functions along its chain, and (iii) a bonding agent between said reinforcing inorganic filler and said elastomer which consists of a polysulphurised alkoxysilane.
    Type: Grant
    Filed: May 25, 2004
    Date of Patent: January 19, 2010
    Assignee: Michelin Recherche et Technique S.A.
    Inventors: Pierre Robert, Samuel Mathieu
  • Rubber composition for a tire tread
    Patent number: 7431061
    Abstract: A cross-linkable or cross-linked rubber composition which is usable to constitute a tire tread having improved wear resistance, to such a tread and to a tire incorporating this tread. The rubber composition is particularly applicable to tires of passenger-vehicle type. The rubber composition includes a plasticizing resin of number-average molecular weight of from 400 to 2000 g/mol, the resin containing units resulting from the polymerization of vinylcyclohexene.

  • Rubber composition for a tire tread
    Patent number: 7084228
    Abstract: A cross-linkable or cross-linked rubber composition usable to constitute a tire tread having improved wear resistance, to such a tread and to a tire incorporating this tread. The composition is particularly applicable to tires of passenger-vehicle type. The rubber composition includes a plasticizing resin of number-average molecular weight of from 400 to 2000 g/mol, the resin having units resulting from the polymerization of a monocyclic or bicyclic unsaturated terpene, in a mass fraction of from 70% to 100%, and having a glass transition temperature greater than 50° C. and less than 120° C.
