    Abstract: A highly filled system is provided which employs the combination of coated filler particles and a compatibilizer to allow extremely high filler loading while maintaining a low viscosity. The compositions of the present invention allows a filler level which was previously unachievable due to the increase in viscosity which is particularly evident when extremely small (nanometer sized) filler is added to a system containing conventional (micron sized) filler particles. This is accomplished through selection of a coating for the filler and selection of a compatibilizer which improves the affinity between the filler and the polymer, thereby improving nanometer sized filler wetting and dispersion and allowing the filler to be incorporated into the polymer matrix.

  • Patent number: 7137423
    Abstract: The invention relates to a tire having at least one component (e.g. tread) of a rubber composition comprised of an amine functionalized styrene/conjugated diene copolymer elastomer (e.g. styrene/butadiene and/or styrene/isoprene/butadiene copolymer elastomer) which contains reinforcement comprised of silanol functionalized particulate carbon black having silica domains covering a fraction of the carbon black surface together with an alkoxysilane polysulfide coupling agent. The silica domains on the carbon black surface contain hydroxyl groups (e.g. silanol groups) on their surfaces which are reactive with the alkoxysilane moiety of the coupling agent. The amine functionalized styrene/butadiene elastomer is an organic solution polymerization prepared elastomer which contains pendant and/or terminal amine groups as one or more of primary amine, secondary amine, tertiary amine, and/or heterocyclic amine groups. The amine functionalized elastomer may be tin coupled.

  • Patent number: 7129287
    Abstract: A method for preparing exfoliated clay nanocomposites by in-situ polymerization comprising the steps of (a) providing a mixture of at least one type of monomer and at least one type of organophilic clay; and (b) initiating an in-situ polymerization reaction in the mixture so as to cause the at least one type of monomer to polymerize thereby forming the exfoliated clay nanocomposite. The exfoliated clay nanocomposite produces an x-ray diffraction pattern that is substantially devoid of an intercalation peak. The exfoliated clay nanocomposite may then be used as a masterbatch.

  • Patent number: 7115677
    Abstract: A flame-retardant resin composition comprises 10 to 300 parts by weight of a flame retardant (B) and 1 to 200 parts by weight of an inorganic filler (C) (a glass fiber and/or a glass flake), relative to 100 parts by weight of a base resin (A). The flame retardant (B) comprises a polyphenylene oxide-series resin and/or a polyphenylene sulfide-series resin (B1), a phosphoric ester (B2), and a nitrogen-containing cyclic compound (B3) (for example, a polyphosphate of an amino group-containing triazine compound). The inorganic filler (C) has been treated with a surface-treatment agent or sizing agent containing a novolak epoxy resin. Such a resin composition is useful for obtaining a shaped article which has been inhibited from dripping and to which flame retardancy is highly imparted.
