  • Patent number: 6881798
    Abstract: Disclosed is a preparation method of an exfoliated nitropolymer/silicate nanocomposite by emulsion polymerization of monomers forming the polymer in an aqueous dispersion of non-modified, layered silicate in the presence of a reactive emulsifier having both a radical-polymerizable vinyl group and a functional group with affinity for silicate. In the process of the polymerization, silicate is fully exfoliated and uniformly dispersed in the polymer. Therefore, only a small amount of silicate is sufficient to improve thermal and mechanical properties of the polymer. Further, the method is advantageous in terms of a simple preparation process due to no use of organo-modified silicate, thus achieving an economic benefit.

  • Publication number: 20040220301
    Abstract: The present invention provides a polymeric-type antistatic agent containing a polymer composition consisting of a polymeric-type antistatic agent containing a resin or/and an elastomer as a main component thereof; or/and a thermoplastic resin having a polar group or/and an elastomer having the polar group. At least one kind of an anion-containing salt, having a fluoro group and a sulfonyl group, is added to the polymer composition without intermediary of a medium consisting of a low-molecular-weight polyether-containing compound or a low-molecular-weight polar compound whose number-average molecular weight is not more than 5000. The present invention also provides a composition, for a conductive roller or the like, containing polymer components and the polymeric-type antistatic agent dispersed in the polymer components.

  • Patent number: 6787592
    Abstract: Organoclays based on specific types of ester quats are found to be remarkably effective for use in preparing nanocomposites. These organoclays comprise the reaction product of a smectite clay and a quaternary ammonium compound (or “quat”) which comprises two esterified radicals hereinafter called a “diester quat”). The diester quat may be present in admixture with further quaternary ammonium compounds having esterified radicals, especially compounds having three esterified radicals (hereinafter “triester quats”); or compounds having a single esterified radical (hereinafter “monoester quats”). Where such a mixture of quats is used, the reaction is between the smectite clay and the quat mixture.

  • Publication number: 20040162369
    Abstract: An adhesive composition which can be formulated to have low or substantially no VOC emissions is provided. Adhesives in accordance with the invention can be formulated as high solids, one-part, reactive, cross-linked adhesives. This can be achieved by utilizing amide-ester-acrylate reactions or reactions with any other carboxylated polymers. Adhesive compositions in accordance with the invention can include oils, such as various drying oils and similarly acting polymers, co-polymers, and fatty acids. Adhesives in accordance with the invention can also include various hydrocarbon resins, particularly crosslinkable hydrocarbons having a melting point in the range 70° C. to 140° C. Cross-linking agents, such as materials with pendant oxazoline groups are also advantageously included. Various other mixing, flow and other handling ingredients can also be included.

  • Patent number: 6777479
    Abstract: Polymer composite materials comprising of least one polymer resin and platelet particles from at least one layered silicate material uniformly dispersed in the resin and articles prepared from the polymer composite materials. The polymer composite contains at least one polyamide resin, at least one oxygen scavenging system, and at least one layered silicate material. These polymer composite materials are especially useful for manufacturing clear polyester bottles and polyester film that are recyclable have improved active gas barrier properties to oxygen, and have improved passive barrier properties to carbon dioxide and other gases. The polymer composite materials can be used in relatively minor amounts as either a blend or a coextruded thin layer with virgin or post consumer recycled polyesters and related copolymners.

  • Patent number: 6770696
    Abstract: Disclosed is a method for preparing a clay-dispersed polymer nanocomposite. In this method, a polymer, which carries oxygen atoms within the repeating units of its backbone and is thermodynamically compatible with a binder resin, is used as a matrix resin. Useful is poly(&egr;-caprolactone) owing to its thermodynamic compatibility with poly(styrene-co-acrylonitrile)copolymers, poly(acrylonitrile-co-butadiene-co-styrene) copolymers, and poly(vinylchloride) resins. Poly(&egr;-caprolactone) resins aid the binder resins to penetrate into silicate layers so that the silicate of the organophilic clay was completely delaminated to silicate lamellas.
