  • Patent number: 5883173
    Abstract: The present invention relates to a latex comprising water and a layered material intercalated with a polymer. The invention also relates to a nanocomposite material comprising a layered material intercalated with a polymer. The latex can be produced by forming a dispersion of layered material in water, adding surfactant, polymerizable monomer or monomers, and a polymerization initiator to the mixture and then polymerizing the monomer to form a latex. The latex can also be formed from preformed polymers. Composite materials formed from latexes produced by either method have improved mechanical properties and reduced air permeability.
    Type: Grant

  • Patent number: 5807629
    Abstract: An elastomeric material nanocomposite having sufficiently low air permeability to be useful as a tire inner liner among other things, can be prepared by dispersing a layered clay material into the elastomer in the form of packets having an average thickness in the range of about 100 .ANG. to about 1400 .ANG.. Accordingly, the present invention provides in one embodiment, a novel composite composition, and in another embodiment, a novel tire inner liner composition.

  • Patent number: 5665183
    Abstract: A tire inner-liner, comprising a solid rubber and a complex, said complex comprising a reactive rubber and a layered silicate clay uniformly dispersed therein. The complex comprising the clays significantly improve the low air permeability of the tire inner-liner without adversely affecting the rubber composition.
