摘要： The present invention discloses intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant monomer surface modifier including an alkyl radical having at least 6 carbon atoms and a polymerizable monomer, oligomer or polymer. The intercalant monomer surface modifier converts the interlayer region of the layered materials from hydrophilic to hydrophobic, therefore, polymerizable monomers, oligomers or polymers can be easily intercalated into the interlayer spacing. The co-presence of the intercalant monomer surface modifier and polymerizable monomer, oligomer or polymer provide an environment for more polymerizable monomers, oligomers or polymers to be intercalated into the interlayer spacing and the intercalates are readily exfoliated into polymer matrices to form nanocomposites. The nanocomposites (e.g., epoxy-clay) prepared from the intercalates demonstrated enhanced mechanical, thermal and chemical resistance compared with pristine polymer matrices.

摘要： Intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant monomer including an alkyl radical having at least 10 carbon atoms and having a dipole moment greater than the dipole moment of water, to sorb or intercalate the intercalant monomer between adjacent platelets of the layered material. Sufficient intercalant monomer is sorbed between adjacent platelets to expand the adjacent platelets to a spacing of at least about 5 .ANG. (as measured after water removal to a maximum of 5% by weight water), up to about 100 .ANG. and preferably in the range of about 10-45 .ANG., so that the intercalate easily can be exfoliated into individual platelets. The intercalated complex can be combined with an organic liquid into a viscous carrier material, for delivery of the carrier material, or for delivery of an active compound; or the intercalated complex can be combined with a matrix polymer to form a strong, filled polymer matrix.

摘要： Nanocomposites are manufactured by combining a host material, such as an organic solvent or a matrix polymer and exfoliated intercalates formed by contacting a phyllosilicate with a polymer to adsorb or intercalate the polymer between adjacent phyllosilicate platelets. Sufficient polymer is adsorbed between adjacent phyllosilicate platelets to expand the adjacent platelets to a spacing of at least about 5 .ANG., preferably at least about 10 .ANG. (as measured after water removal), up to about 100 .ANG. and preferably in the range of about 30-40 .ANG., so that the intercalate easily can be exfoliated, e.g., when mixed with an organic solvent or a polymer melt, to provide a carrier material for drugs and the like, or to provide a matrix polymer/platelet composite (nanocomposite) material--the platelets being exfoliated from the intercalate.

摘要： A new and improved method of manufacturing an acrylic acid superabsorbent polymer, that is manufactured by any known technique, except that the acrylic acid monomer is polymerized to substantial completion before neutralization, and neutralization is accomplished by admixing a solid, e.g., powdered or granular, neutralizing agent into the acrylic acid polymer. Preferably, the neutralizing agent is a solid, non-hydroxide neutralizing agent, such as sodium carbonate, potassium carbonate, ammonium carbonate or mixtures thereof. Cross-linking may be accomplished during polymerization, simultaneously with neutralization, or cross-linking may be carried out in a separate processing step subsequent to neutralization, or both.

摘要： A process for decreasing the concentration of phenothiazine from a solution of acrylic acid by contacting the acrylic acid solution with a hydrophobic clay, such as an organophilic clay; or by protonating the phenothiazine, oxidizing the phenothiazine, and contacting the protonated, oxidized phenothiazine with a hydrophilic clay, such as an acid-activated smectite clay or sodium bentonite clay to sorb (absorb and/or adsorb) the phenothiazine into or onto the clay. Once sorbed onto the smectite clay, the phenothiazine easily can be removed, together with the clay, from the solution of acrylic acid, e.g., by filtration.

摘要： The present invention is directed to a porous copolymer micro-particle having a high oil absorbency. The method of the present invention comprises the steps of: dissolving at least two polyunsaturated monomers in a water-immiscible organic solvent to provide a monomer mixture containing at least about 60%, preferably about 100% by weight polyunsaturated monomers; adding the monomer mixture to an aqueous solution, preferably having an effective amount of a suspension stabilizer dissolved therein, to form an organic/aqueous biphasic liquid system; vigorously agitating the biphasic liquid system at a rate sufficient to cause the water immiscible organic phase to be suspended as micro-droplets in the aqueous phase; continuing vigorous agitating during polymerization of the monomers in the suspended micro-droplets to produce a microporous polymer micro-particle; and separating the microporous polymer micro-particle from the organic solvent to produce a microporous and oil sorbent polymer micro-particle having a mean unit diameter of less than about 25 microns.

摘要： A method of treating a water-swellable clay after the clay has been mined and dried to improve its properties when in contact with contaminated water. After the common initial drying of the clay to a moisture content of 12% by weight or less, the clay is impregnated with an aqueous solution containing a dissolved, water-soluble polymer, in an amount of at least about 0.5% by weight based on the dry weight of the clay, and the clay is wetted to a moisture content of more than 12% by weight, preferably at least about 15% or more, based on the dry weight of the clay, and then redried to a moisture content of 12% by weight or less, based on the dry weight of the clay. This rewetting step to hydrate and polymer-impregnate the clay, and then redrying the clay, unexpectedly improves the contaminated water absorbency, and viscosity properties when the clay is in contact with contaminated water; unexpectedly increases the rheology properties of the clays for oil well drilling fluids and lost circulation fields when contaminated water is encountered during drilling, enhances the clay properties when used as a suspending agent in the cosmetics and pharmaceutical industries when the composition contains a dissolved, inorganic salt and/or an organic liquid; and provides unexpectedly increased contaminated water-absorption in forming water-swellable clay-based water barriers.

摘要： Geocomposite articles that can provide a barrier against high conductivity water e.g., ocean water, are described and their method of manufacture, for waterproofing surfaces that contact high conductivity water. The geocomposite article mat includes a woven or non-woven geotextile sheet or mat containing a powdered or granular partially cross-linked acrylamide/acrylate/acrylic acid copolymer across its entire major surface(s). The powdered or granular copolymer has an unexpectedly high free-swell when hydrated with High Conductivity water, such as ocean water. A liquid-impermeable cover sheet is adhered to the upper major surfaces of the filled copolymer-carrying geotextile to provide a primary high conductivity water barrier layer that, if ruptured, is sealed by the swell of an underlying layer of water-insoluble, partially cross-linked acrylamide/acrylic acid copolymer.
