    摘要: There is provided a processing method for effectively and promptly removing insoluble components contained in a solution of a styrene resin waste material to enable regeneration of high-quality regenerated styrene. To this end, a solution of the styrene resin waste material in an organic solvent is processed with, for example, a dehydrating agent, to remove insoluble components. The resulting clarified solution is degasified on heating in vacuum to remove the organic solvent for recycling the resulting mass as a regenerated styrene resin. The insoluble components include foreign matter, such as moisture, sludge and colorant agents. By this processing method, it becomes possible to recycle high-quality regenerated styrene.

    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: 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.
