Resin composition, molded article, laminate, gas barrier material, coating material and adhesive

The present invention, in an aspect, provides a resin composition that contains a vinyl polymer and a smectite with partially immobilized lithium.

Resin composition, molded article, laminate, gas barrier material, coating material, and adhesive

A resin composition contains a polyester polyol and a smectite with partially immobilized lithium.

Resin composition, molded body, laminate, gas barrier material, coating material, and adhesive

A polyester resin composition according to the present invention includes a polyester polyol having a glycerol skeleton and a curing agent, wherein 5 percent by mass or more of glycerol residue of the polyester polyol is contained in the polyester resin composition. The resin composition can provide an adhesive exhibiting an excellent adhesive force. The adhesive has a gas barrier property or a water vapor barrier property and, therefore, a gas barrier or water vapor barrier film can be provided by using the adhesive.

Polyester resin composition, adhesive and film

An oxygen-barrier film and an adhesive used therefor. Provided are an adhesive, which can be used for packaging foodstuffs and contains mainly a polyester having excellent oxygen-barrier properties, and an oxygen-barrier film that uses the adhesive. The oxygen-barrier film is prepared using an adhesive that includes: an amorphous polyester polyol, which is obtained by polycondensation of a polyvalent carboxylic acid component including at least one type of ortho-oriented aromatic dicarboxylic acid or anhydride thereof, and a polyhydric alcohol including at least one compound selected from the group consisting of ethylene glycol, propylene glycol, butylene glycol, neopentyl glycol and cyclohexanedimethanol, and a curing agent capable of reacting with the amorphous polyester polyol.

Oxygen-barrier film and adhesive

An organic-inorganic composite material is disclosed wherein an inorganic compound is finely dispersed in an organic polymer matrix in nanometer order and the inorganic compound content is large. The organic-inorganic composite material has formability and flexibility of organic materials and features of various metal compounds (such as hardness, catalytic power, insulating property, semiconducting property, electronic conductivity, ionic conductivity, large specific surface area, high heat resistance, wear resistance, and dimensional stability to temperature changes or moisture absorption) at the same time.

Organic-inorganic composite material and method for producing the same

An ion conductor has fine particles of an organic polymer including 20 to 80% by mass of ultra-fine particles of an inorganic compound, and an electrolytic solution impregnated into the fine particles of the organic polymer, wherein the fine particles of the organic polymer have a specific surface area measured by the BET method of 30 m/g or more.

Ion conductor and electrochemical display device utilizing the same

A loudspeaker in which the input resistance is improved and the effect of humidity on the playback frequency response is suppressed, and a method for the preparation of the loudspeaker. A sheet-like product, containing glass particles with a particle size of 8 nm to 300 nm and polyamide resin, and prepared by application of a paper-making technique, is used as the diaphragm. The content of the glass particles in the compound material is 5 weight % to 70 weight %. In preparing the diaphragm, a phase of an aqueous solution containing diamine and water glass is contacted with a phase of an organic solution containing a dicarboxylic acid halide to generate a compound material containing glass particles and the polyamide resin. The compound material so prepared is formed into a sheet by a paper-making technique. In the process of the preparation by the paper-making technique, the compound material mixed with other fibrous material may also be used as a starting material.
