PROBLEM TO BE SOLVED: To provide an oxidizing agent which is useful as the oxidizing agent for producing an electrically-conductive polymer by oxidative polymerization, has high electric conductance, and is suitable for producing an excellently heat-resistant electrically-conductive polymer, and to provide a method for producing the same. SOLUTION: The oxidizing agent for producing the electrically-conductive polymer comprises an organic sulfonic acid iron (III) salt, wherein the organic sulfonic acid iron (III) salt contains the iron (III) at a stoichiometrically excess quantity than the organic sulfonic acid, and the organic sulfonic acid salt and the iron (III) salt have an equivalent weight ratio of 1:1.02 to 1:1.5. The method for producing the oxidizing agent is a method wherein iron (III) sulfate and an organic sulfonic acid are used as starting materials to have a ratio of 1.02-1.5 equivalent of the former relative to 1 equivalent of the latter, and are reacted in a solvent to synthesize the organic sulfonic acid iron (III) salt.

PROBLEM TO BE SOLVED: To provide a highly dispersed solid-liquid dispersion which enhances the dispersibility of inorganic powder in organic solvents without adding a dispersant. SOLUTION: This solid-liquid dispersion comprises an organic solvent and inorganic powder whose surface is treated with two kinds of silane coupling agents comprising a silane coupling agent having fluorine atoms in the molecule and a silane coupling agent having a silicon-nitrogen bond in the molecule. The mass ratio of the silane coupling agent having the fluorine atoms in the molecule to the silane coupling agent having the silicon-nitrogen bond in the molecule is preferably 70:30 to 30:70. The inorganic powder is preferably fine particulate titanium dioxide or fine particulate zinc oxide having an average primary particle diameter of 5 to 200 nm. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a flame-retardant synthetic resin composition containing flame-retarding layered double hydroxide dispersed in a matrix resin in a delaminated state. SOLUTION: The flame-retardant synthetic resin composition contains a flame-retarding effective amount of a layered double hydroxide comprising a basic layer composed of a metal double hydroxide expressed by formula (I): M(II) 1-x M(III) x (OH) 2 (M(II) is Mg, Zn or their mixture; M(III) is Al; and x is 0.2-0.33), an acetic acid salt of Mg, Zn or Ce intercalated in the intermediate layer of the basic layer and interlaminar water and is reversibly delaminated in water. The synthetic resin is a polycondensation resin containing a raw material releasing the layered double hydroxide in the production process of the resin, and the layered double hydroxide is uniformly dispersed in the synthetic resin in delaminated state by adding the double hydroxide to the raw material during the production process of the synthetic resin.

Abstract:
PROBLEM TO BE SOLVED: To provide a surface treated product of finely-powdered titanium oxide or finely-powdered zinc oxide, having excellent dispersibility and scarcely increasing viscosity even when mixed into a cosmetic or silicone oil slurry in a large amount in case of preparing them. SOLUTION: This product of the finely-powdered titanium oxide or the finely-powdered zinc oxide coated with a mixture of dimethicone and a dimethicone/methicone copolymer is obtained by using finely-powdered titanium oxide or finely-powdered zinc oxide having an average particle diameter of 5-100 nm as a base material, adding the mixture of the dimethicone and the dimethicone/methicone copolymer given by mixing them in a mass ratio of 10:1 to 10:5 to the base material, and coating surfaces of the finely-powdered titanium oxide or the finely-powdered zinc oxide composing the base material with the mixture of the dimethicone and the dimethicone/methicone copolymer in an amount of 10-30 mass% based on the base material. The silicone oil slurry is obtained by dispersing the product in a silicone oil. The cosmetic is obtained by being compounded of the slurry. COPYRIGHT: (C)2007,JPO&INPIT
