摘要： A sheetlike absorbent material is produced by reducing the water content of a hydrogel of a hydrophilic cross-linked polymer under pressing (milling) and feeding. A gel composition comprising, for example, a hydrogel containing a cross-linked poly(meth)-acrylic acid (salt), glycerol (polyhydric alcohol), and polyester fibers (molding assistant) onto a dryer drum on the upperstream side of a press roller, whereby the gel composition is pressed (milled) and heated by the press roller to give a sheet with at least one surface thereof smoothed. The absorbent material produced by the above process is excellent particularly in absorption characteristics such as absorption speed and absorption factor under pressure and shape retention.

摘要： A process for the production of a water absorbent powder which comprises adding a nucleophile to a water absorbent powder made from a carboxylated resin, which is cross-linked with an epoxy crooslinking agent in the neighborhood of the surface and contains a residual cross-linking agent, in a heated state to thereby reduce the content of the residual cross-linking agent in the powder. The above process characterized by reducing the content of the residual cross-linking agent in the powder by adding a nucleophile to the powder in a heated state can constantly give a novel water absorbent powder satisfying all of the three requirements, i.e., an enhanced coefficient of water absorption under high pressure, a lowered content of residual cross-linking agent and an enhanced rate of absorption, as compared with the water absorbent resins of prior art which are cross-linked in the neighborhood of the surfaces. The powder can be used particularly preferably for sanitary goods such as paper diaper, sanitary napkin and so on.

摘要： A method of recovering ethylene sulfide by continuously distilling a feedstock solution containing ethylene sulfide, toluene (a hydrophobic organic compound) having a boiling point higher than that of ethylene sulfide, a compound having a boiling point higher than that of toluene, and water with the use of a continuous distilling column (2), a distilling column (4) and a rectifying column (5). Ethylene sulfide is recovered by distillating ethylene sulfide together with toluene and water out of the column (2), separating the distillate into oil and water layers in a separating tank (3), distilling continuously the oil layer in the column (4) without refluxing to distil out part of ethylene sulfide together with water, and rectifying the bottom of the column (4) in the column (5). This method makes it possible to inhibit ethylene sulfide polymerization, to separate and recover the sulfide continuously, efficiently and stably, and to evade plugging of various columns and pipings.

摘要： A water-absorbent resin is produced by dispersing a solid blowing agent with an average particle diameter in the range of 1 to 100 mu m in an aqueous solution containing an unsaturated monomer and a cross-linking agent and polymerizing the monomer. The resin is excellent in the ability to diffuse aqueous liquids and in water absorption characteristics such as the rate of water absorption, water retention capacity and dry touch, and is reduced in the contents of water-soluble components and residual monomers. Sanitary materials prepared from a composition of this resin are improved in the rate of water absorption and water retention capacity and can avoid leakage.

摘要： A process for producing a photosensitive resin by the reaction of the carboxyl groups of a resin (A) having at least two (meth)acryloyl groups and at least one carboxyl group in its molecule with a difunctional epoxy resin (B) having two epoxy groups in its molecule. As the obtained resin comprises linear high-molecular-weight resin (A) blocks formed via the resin (B) block, it is excellent in tackfreeness and can be formed into a resist film. This film can be developed, after being irradiated with light, with an aqueous alkali solution rapidly and accurately. Therefore it has become possible to provide a high-performance liquid photosensitive resin composition useful for forming a solder resist for producing printed wiring boards, an electroless plating resist, a black matrix for liquid-crystal display panels, and a color filter. A liquid photosensitive resin composition containing minute particles of a polymer having a Tg of 20 DEG C or below gives a coating film which, after being photocured, is excellent in tight adhesion even when subjected to thermal history.
