According to the present invention, a water absorbent material and materials to be sucked included in a water permeable bag type member form a water absorber. Thus, the water absorber is small both in weight and volume upon its transportation, and accordingly, the water absorber can be rapidly conveyed in large quantities without depending on a human power. The water absorber absorbs water upon its use to adequately satisfy a function of a form traceability for weight, volume and outline.
摘要:
An antimicrobial agent utilizes a resin having acrylonitrile and styrene and/or a conjugated diene as units. The antimicrobial agent includes a metal-salt-containing copolymer, and the metal-salt-containing copolymer is obtained by treating a copolymer containing acrylonitrile and at least one of styrene and a conjugated diene as units with an acid to thereby introduce acid radicals into the copolymer, and converting at least part of the acid radicals into a salt of at least one metal selected from among Ag, Cu, and Zn.
摘要:
A method of manufacturing a polyelectrolyte having the step of sulfonating polystyrene resin in a state where the polystyrene resin has been dissolved or dispersed in solvent composed of alicyclic compounds.
摘要:
A water-absorbing resin having superior water absorption properties, and a method for manufacturing the water-absorbing resin having superior water absorption properties in a short time, in which used waste materials are used for effective utilization of resources. To this end, a high-molecular material containing acrylonitrile, styrene and conjugated dienes as constituent units are processed with acid and/or alkali.
摘要:
A high-molecular flocculant rendered water-soluble by conversion of cyano groups contained in a high-molecular material, a method for producing the flocculant, and a method for efficiently processing water using the flocculant. A high-molecular material containing acrylonitrile as a monomer is processed safely to impart hydrophilicity to the material and the resulting product is used for water processing to contribute to environmental conservation. An amino compound is added to a cyano group containing high-molecular material to convert at least a portion of the cyano group (—C≡N) into a molecular structure portion having an imidamino structure and, if necessary, to convert at least the portion into one of an acid salt, a quaternary ammonium salt or a hydrolyzate structure portion to give a high-molecular flocculant. Alternatively, a high-molecular material having cyano groups is hydrolysed to convert the cyano group into carbamoyl groups, carboxylic groups or their salts to give a high-molecular flocculant. This high-molecular flocculant is charged alone or in combination with commercial flocculants into the water for processing.

A polymer electrolyte which contains an inorganic pigment, having a sulfonated polystyrene resin as a principal ingredient, and is soluble to water.
摘要:
A water-immersed switch which does not conduct electricity in the absence of a dielectric liquid, such as water, and which conducts electricity in the presence of the dielectric liquid. The water-immersed switch includes a modified copolymer containing acrylonitrile and at least one of styrene and/or a conjugated diene, as constituent units, and acidic groups introduced into said modified copolymer, and a plurality of electrically conductive electrodes.
