  • Publication number: 20150011675
    Abstract: The present invention aims to develop an aqueous heat-shielding coating material to which low staining properties are imparted to suppress a reduction in heat-shielding properties due to the reduction in solar reflectance caused by adhesion of contaminants in the air during outdoor exposure, thereby maintaining the heat-shielding properties for a long period of time. The above problem is solved by providing a resin composition for an aqueous coating material including: (A1) a water-soluble and/or water-dispersible resin; (A2) a heat-shielding pigment; (B1) an organosilicate and/or a modified product of the organosilicate; and (B2) a curing catalyst that promotes a hydrolysis/condensation reaction of an alkoxysilyl group.

  • Patent number: 4439322
    Abstract: A membrane for microfiltration, ultrafiltration or dialysis comprises a methyl methacrylate copolymer containing about 0.5 to 10 mol % of a monomer having sulfonate groups, and a methyl methacrylate copolymer containing about 0.5 to 10 mol % of a monomer having quaternary nitrogen-containing groups. It is manufactured by mixing those copolymers, dissolving the mixture in a solvent such as dimethylsulfoxide or dimethylformamide, and forming a membrane from a solution of the copolymers by casting or spinning. The membrane is particularly suitable for use in the purification of blood, and its most preferable form is hollow fibers. A method of preparing hollow fibers comprises extruding the copolymer solution through a spinneret having an annular orifice defined by a thin central tube while a liquid or gas is being injected into the central tube, and coagulating the extrusion product.
