    摘要: A layered molding and method for making the same which has excellent anti-permeability to gasoline. The layered molding is defined by a fluoroplastic or polyamide plastic and an epichlorohydrin rubber. The fluoroplastic is a copolymer formed from at least two precursors selected from the group consisting of hexafluoropropylene, tetrafluoroethylene, and vinylidene fluoride, which are selected within a plotted range to preferably form a binary or tertiary composition. The epiclorohydrin rubber contains organic phosphonium. The resulting molding layer does not require an adhesive agent.

    摘要: The present invention provides a method of manufacturing a composite material made of a rubber and a clay mineral dispersed uniformly therein. The method proceeds exchanging inorganic ions of the clay mineral with organic onium ions to organize the clay mineral; mixing the organized clay mineral and a process oil and/or a plasticizer; and mixing the rubber material with the mixture of the organized clay mineral and the process oil and/or the plasticizer. Process oil and/or plasticizer are intercalated into the organized clay mineral. As a result, the interlayer distance of the clay mineral is enlarged. The most favorable mode of the present invention is for a barrier material against water, gas and the like and for a rubber material required for an improved mechanical property.

    摘要: An ethylene propylene rubber blend containing an ethylene-.alpha.-olefin-diene copolymer as the rubber component of the blend. The ethylene-.alpha.-olefin-diene copolymer has a propylene content of about 43% to about 51% by weight, an iodine value of about 33 to about 39, a Mooney viscosity (ML.sub.1+4 100.degree. C.) of about 34 to about 44, and a molecular weight distribution (M.sub.W /M.sub.N) of about 5 or less. The ethylene propylene rubber blend can be used, for example, for formulating articles such as hoses, and in particular brake hoses. At least an inner tube provided inside the hose is preferably formed of the ethylene propylene rubber blend. The ethylene propylene rubber blends have a modulus of elasticity not significantly dependent upon temperature and are excellent in compression set and processability.

    摘要: Provided is a production method of a β-type sialon fluorescent substance, where luminescence intensity can be improved without adding a metal element other than elements composing a β-type sialon fluorescent substance. Namely, in a production method of a fluorescent substance containing an optically-active element as the luminescence center in a crystal of nitride or acid nitride, a β-type sialon fluorescent substance is produced by a burning process for heat-treating a mixture including metal compound powder and an optically-active element compound; a high-temperature annealing process for heat-treating the burned product after cooling under a nitrogen atmosphere; a rare-gas annealing process for heat-treating the high-temperature annealed product under a rare gas atmosphere; and a process for treating the rare-gas treated product with an acid.
