  • Patent number: 8026339
    Abstract: A polysulfone is provided with a nitrogen-containing functional group having an affinity to an acid, an electrolyte membrane using the polysulfone, and a fuel cell including the electrolyte membrane. In particular, the polysulfone includes a nitrogen-containing functional group that has an affinity to an acid, such as a phosphoric acid, thereby having an excellent acid retaining ability. In an electrolyte membrane including the polysulfone and an acid, the amount of the retained acid can be controlled. Therefore, the electrolyte membrane has a high ionic conductivity and a high mechanical strength. A polysulfone blend of polysulfone and a thermoplastic resin prevents the dissolution of polysulfone by phosphoric acid, so that an electrolyte membrane using the polysulfone blend has an improved durability. A cross-linked reaction product of polysulfone, a cross-linking agent and a polymerization product of polysulfone, a thermoplastic resin, and a cross-linking agent strongly resist a phosphoric acid.

  • Patent number: 5703258
    Abstract: A flame retardant organic silicon and phosphorus containing compound is produced by reacting a silicon halides compound with an organic phosphorus compound to produce an organic silicon and phosphorus halides compound which is then reacted with an organic compound to produce an organic silicon and phosphorus containing compound. This organic silicon and phosphorus containing compound is incorporated in an otherwise more flammable organic material under reaction conditions and in an amount sufficient to reduce the combustibility of the otherwise more flammable organic material. The organic silicon and phosphorus containing compound may also be utilized as coating agents, adhesives, surfactants, insecticides, hydraulic fluid and other uses.

  • Patent number: 5597557
    Abstract: A process for making solid colored particles by preparing a reaction solution in water comprising formaldehyde, urea, a cyclic polyamine functional triazine compound, and acid. A dye can be incorporated into the reaction solution if a color other than white is desired. Particles are formed having an average particle size between 1 and 70 microns without the need to resort to crushing to break up agglomerates. Particles made by this process provide excellent color and are easily washable from a substrate when incorporated into a washable formulation.Additionally, it has been found that the incorporation of colored microcapsules of average size of 1-70 microns where the color is located primarily on or in the shell of the microcapsule also provides excellent washable compositions when incorporated into a washable formulation.
