    摘要: A composite clay material with the interlayer distance sufficiently expanded by dispersing clay mineral in a low polar polymer on a molecular level and the method for producing the same, blend material and composite clay rubber material using the same and the production method thereof.The composite clay material is formed of a clay mineral rendered compatible with an organic material through ionic bonding to an organic onium ion having 6 or more carbon number and a main guest molecule having a polar group in its main chain and side chain and molecular length equal to or larger than that of said organic onium ion. The main guest molecule is incorporated at least partially into an interlayer section of the clay mineral which has a hydrogen bonding with the polar group of the main guest molecule. The main guest molecule preferably has a molecular weight ranging from about 100 to 100000. Alternatively a first guest molecule having a polar group and molecular length equal to or smaller than that of the organic onium ion and a second guest molecule having no polar group therein and molecular length larger than that of the organic onium ion are incorporated into the interlayer section of the clay mineral instead of the main guest molecule. The above obtained clay composite material may be mixed with the rubber material.

    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: Star-shaped nylons with low melt viscosities and excellent mechanical properties, methods for their preparation, a novel tetrasubstituted carboxylic acid for use as a polymerization core therefor and methods for its preparation are provided.A star-shaped nylon has polymer chains emanating from 3 or more polymerization initiation groups which are substituents bonded to every other or more separated carbon atoms on an aromatic ring of an aromatic compound. The star-shaped nylon is produced by homogeneously mixing the aromatic compound with molten nylon monomer and polymerizing the nylon monomer with the respective polymerization initiation groups as the starting points. A novel tetrasubstituted carboxylic acid having a structure of 3,5,3',5'-biphenyltetracarboxylic acid is useful as a polymerization core for star-shaped nylons.

    摘要: This invention provides liquid crystal compositions for light controlling materials of light scattering type having both memory and high speed response characteristics. The composition neither needs a temperature controlling device nor a device for imparting a shear stress as a memory erasing device, because the composition comprises a two-frequency addressing liquid crystal or such liquid crystal with an ionic component. The two-frequency addressing liquid crystal responds to an electric field and exhibits a positive dielectric anisotropy or a negative dielectric anisotropy depending on the frequency region of the electric field. Because the flat shaped particles of the present invention exhibit an affinity with the liquid crystal, the particles are dispersed in the liquid crystal and form liquid crystal domains effectively.
