Abstract: An electrode mixture layer composition for a nonaqueous electrolyte secondary battery contains an active material, water and a binder. The binder contains a crosslinked polymer of a monomer component including an ethylenically unsaturated carboxylic acid monomer, and a salt thereof. The crosslinked polymer is a polymer that is crosslinked with allyl methacrylate, and an amount of the allyl methacrylate used is 0.1 to 2.0 parts by weight relative to total 100 parts by weight of non-crosslinking monomers, and a content of the crosslinked polymer and salt thereof is 0.5% to 5.0% by weight of the active material.

Abstract: A binder for nonaqueous electrolyte secondary battery electrodes, which contains an acrylic crosslinked polymer or salt thereof, and which is characterized in that: the acrylic crosslinked polymer contains, in all the constituent monomers thereof, 30-90% by weight of an ethylenically unsaturated carboxylic acid monomer (component (a)) and 10-70% by weight of an ethylenically unsaturated monomer containing no carboxyl group and having an SP value of a homopolymer of 9.0-12.5 (cal/cm3)1/2 (component (b)); and the ratio of monomers having a ratio of an acryloyl group of the total constituent monomers is 70% by weight or more.

Abstract: Disclosed is a fungicide for agricultural and horticultural use which is characterized by containing an inorganic copper compound and a polymer thickener having a sulfonyl group. This fungicide for agricultural and horticultural use exhibits higher plant disease-control effects than conventional inorganic copper-based fungicides.

Abstract: The object of the invention is to provide an aqueous coating agent which I applied onto a recording medium in the ink-jet system to form a film excellent in scratch resistance, water resistance and gloss on the surface of an image, and an aqueous coating solution containing this aqueous coating agent.

Abstract: To provide a dispersing agent that contains a water-soluble polymer that has excellent dispersibility and stability over time even for a high concentration of a dispersoid such as a pigment and can give a pigment slurry having stable viscosity characteristics and redispersibility due to a large dispersion stabilization effect. A dispersing agent containing a water-soluble polymer and/or an alkali metal salt or an ammonium salt of the water-soluble polymer, the water-soluble polymer containing (A) an ethylenically unsaturated monocarboxylic acid monomer or an anhydride thereof, or an ethylenically unsaturated dicarboxylic acid monomer or an anhydride thereof, and (B) a polyether compound, a ratio [(B)/(A)] of the number of moles of alkylene oxide added in component (B) relative to the number of moles of carboxyl group in component (A) being no greater than 0.6, and component (B) being less than 25 wt % relative to the total amount.

Abstract: The present invention relates to a method for producing porous ceramic, the method including molding a mixture containing a water absorbent polymer particle, a ceramic raw material, and water, the water absorbent polymer particle having a water absorption amount in a range of 5 to 30 ml/g at a pressure of 980 Pa, and heating and baking the resulting molded product. The water absorbent polymer particle is preferably composed of a polymer having a 2-acrylamide-2-methylpropanesulfonic acid unit or an acrylamide unit as a constituting monomer unit.
