  • Publication number: 20080187741
    Abstract: The invention provides in-mold decorated articles and methods to form the articles. The in-mold decorated articles include a polymeric portion having a substrate material adhered to a surface of the polymeric portion. The substrate material may be, for example, a film or a fabric. In some embodiments, the polymeric portion may be a foam and, particularly, a microcellular polymeric material. The articles are formed by injecting a mixture of blowing agent and polymeric material into a mold cavity in which the substrate material is disposed, so that the substrate material is forced against a wall of the mold cavity. The blowing agent, which in certain preferred cases is a supercritical fluid, decreases the viscosity of the polymeric material and, therefore, enables reductions in injection pressures and temperatures.

    Abstract: A process for synthesizing polymer foam. Polymer foams can be created through the direct mixing of chemicals. Prior research has shown that greater uniformity can be created by physically mixing the components of the foam before and during the foaming process.

  • Patent number: 7390474
    Abstract: Conventional porous carbon materials obtained by carbonizing an organic gel were prone to shrinkage during their manufacture, in the course of which the density rose and the specific surface area decreased. Another problem was that density and specific surface area were difficult to control after an organic gel had already been formed. In the present invention, a carbon material with a large specific surface area is formed by forming a composite porous material having a reticulated skeleton and composed of a dry gel of an inorganic oxide, and taking advantage of the reaction of this dry gel of an inorganic oxide as a structural support. In one method, a carbon material is formed in this reticulated skeleton in a state in which the characteristics of a dry gel of an inorganic oxide with a large specific surface area are maintained.

  • Patent number: 7182897
    Abstract: A method of storing a material into which a gas saturates, before the material is foamed in a metal mold. The material into which a gas saturates is stored at a predetermined ambient pressure and predetermined ambient temperature to maintain a gas saturated state, thereby preventing escape of the gas from the material into which the gas saturates.

  • Patent number: 7091253
    Abstract: The present invention provides a production process by which a water-absorbent resin of excellent quality can be obtained at a low cost by reasonable steps in aqueous solution polymerization. The process for producing a water-absorbent resin comprises the step of polymerizing an aqueous solution of water-absorbent resin-forming monomers including acrylic acid and/or its sodium salt as major components, wherein: (1) the aqueous solution has a monomer component concentration of not less than 45 weight %; (2) the polymerization is carried out while water is evaporated so that the ratio (concentration ratio) between a solid component concentration in a hydropolymer as formed by the polymerization and a solid component concentration in the aqueous monomer solution will not be less than 1.10; and (3) the solid component concentration in the hydropolymer as formed by the polymerization is not more than 80 weight %.
