    Abstract: Nanocomposites may be produced by mixing dispersions of polymers and dispersions of clay minerals. After mixing, the dispersions may be destabilized with the addition of appropriate compounds. The flocculated solid material exhibits characteristics of a nanocomposite, such as exfoliation of the clay mineral platelets as indicated by x-ray diffraction analysis.

    Abstract: An oil base environmentally benign drilling fluid composition having a stable high viscosity and high gel strength at use temperatures of up to at least 450 DEG F. The drilling fluid includes a low toxicity biodegradable oil vehicle, and as a viscosifying agent an organoclay which is the reaction product of a mineral clay mixture and an alkyl quaternary ammonium salt. The mineral clay mixture comprises at least 50 % by weight of a mineral clay selected from the group consisting of sepiolite, palygorskite and mixtures of sepiolite and palygorskite; and substantially the balance of the mixture is a smectite. Conventional additives such as emulsifiers and fillers may also be present in the drilling fluid.

    Abstract: The composition comprises an aromatic unsaturated monomer having an amount of an organoclay dispersed therein. The organoclay comprises the reaction product of a smectite type clay and quaternary ammonium compounds. The latter are an admixture of (a) a dimethyl di(hydrogenated tallow) ammonium compound and (b) a dimethyl benzyl(hydrogenated tallow) ammonium compound. The organoclay has a quarternary ammonium compound to clay milliequivalent ratio, by weight, of at least 95, and more generally can be up to at least as high as 140, expressed on a 100 % active clay basis. The cross-linkable unsaturated polyester further comprises a liquid unsaturated polyester mixed with the monomer. The amount of organoclay in the monomer and the amount of (a) and (b) are amounts sufficient to produce a cross-linkable polyester composition having a thixotropic index of at least about 2.5, and preferably of at least about 3.0. This invention also provides for the aromatic unsaturated monomer, and for processes for producing the cross-linkable polyester and the aromatic unsaturated monomer.

    Abstract: Organoclay compositions which comprise the reaction product of a smectite-type clay having an ion exchange capacity of at least 50 meq. wt. per 100 g. clay (active basis), and an alkoxylated quaternary ammonium compound having one or two alkoxylated chains containing 0-10 moles ethylene oxide and 3-15 moles of propylene or butylene oxide residues are useful thixotropic materials, especially for the preparation of aqueous systems.
