Abstract
PURPOSE: To obtain the titled moldings excellent in retension of shape, strength, etc. when water is absorbed, suitable for dehydration of soil, etc. by pressing, heating and molding a powdered highly water-absorbable resin with addition of a powdered hydrophilic resin of specified shape and swelling agents for the both resins.
CONSTITUTION: 100pts.wt. Powdered highly water-absorbable resin (A) (e.g., a resin obtd. by reacting a cyclic acid anhydride with a polyvinyl alcohol polymer) is mixed with about 5-100pts.wt. powdered hydrophilic resin (B) (e.g., a polyvinyl alcohol polymer) melting or dissolving in a swelling agent when heated, about 5-50pts.wt., based on 100pts.wt. said both resins A and B, swelling agents (C) for said both resins (e.g., water or propylene glycol) and, if necessary, a crosslinking agent (D) for the resin B (e.g., methylolurea). The purpose resin moldings are obtd. by heat treatment after press molding or hot press molding of the resulting mixture.
