  • Patent number: 7205361
    Abstract: A particulate hydrophobic polymer produced by reacting (A) a particulate crosslinked polymer having a hydroxyl group with (B) a crosslinkable epoxy compound, hydrolyzing the epoxy bonds, and then reacting the obtained compound having a hydroxyl group with (C) an epoxy compound having from 6 to 40 carbon atoms in total, a production process therefor, a column for reversed-phase liquid chromatography, and an analysis method using the column. By using the particulate hydrophobic polymer of the present invention having a remarkably high acid/alkali resistance, a sharp chromatogram for polycyclic aromatic compounds is obtainable with the swelling and shrinkage of the particulate polymer itself reduced and without reducing the column efficiency among various solvents even when the eluent in the column is variously exchanged.

  • Patent number: 7101937
    Abstract: Macromolecules in the shape of three-dimensional kites, barbells, and other shapes are disclosed. The shaped macromolecules are prepared the reaction of one or more dendritic polymers and a linear polymer. The kite-shaped macromolecules are dendritic polymers attached at either their focal points or at an outer to a long carbon chain group. The barbell macromolecules have dendritic polymers at either end of the molecule, which polymers are connected together through the focal points of each by a suitable connecting substituent such as a linear polymer. The shaped macromolecules are used in specialty medical and technological applications including such as drug delivery agents, imaging materials, molecular devices, thin film devices, surface modifiers, transport agents, compatibilizers, rheology control agents, molecular ball bearings, molecular dipoles, non-linear optical materials, medical imaging agents, membrane and cell modifiers, complexing agents, adhesives, interface strengthening agents, and the like.

  • Patent number: 7067586
    Abstract: Block copolymers are prepared by living-type or semi-living type free radical polymerization, with said copolymers having at least one random block comprised of at least one hydrophobic monomer and at least one hydrophilic monomer. The selection of hydrophobic and hydrophilic monomers in the random block is determined by the relative hydrophobicity of the monomers to impart selected solubility or dispersability in water and/or alcohols of the overall block copolymer.

  • Patent number: 6777492
    Abstract: The graft copolymer (G) of the present invention is a graft copolymer which is prepared by emulsion graft polymerization of a rubber polymer comprising 0-50% by weight of a butadiene unit and 50-100% by weight of a (meth)acrylate unit and at least one monomer selected from aromatic alkenyl compound, methacrylate, acrylate and vinyl cyanide compound, said graft copolymer containing 0.5-2.0% by weight of an emulsifier residue. The thermoplastic resin composition containing the graft copolymer of the present invention causes less gas evolution during the molding, provides a molded article with good gloss of molding, and has excellent weather resistance, impact resistance and fluidity.

  • Patent number: 6586533
    Abstract: Articles are formed from a thermosetting composition based on polybutadiene or polyisoprene resins which are subjected to a high temperature cure step of greater than 250° C. The thermosetting compositions may include fillers such as particulate ceramic fillers and may also include woven webs for improved dimensional stability and decreased brittleness. The formation process of this invention is particularly well suited for making electrical circuit substrates for microwave and digital circuits, typically in the form of the thermosetting composition being laminated on one or both opposed surfaces to metal conductive foil (e.g., copper).
