Abstract

PURPOSE: To obtain the titled material useful for the preparation of a variety of water-absorbing materials, by subjecting an α,β-unsatuated carboxylic acid to a W/O type reversed phase suspension polymerization in the presence of a crosslinking agent by using, a carboxyl group-containing polymer having affinity for organic solvents as a dispersant.
CONSTITUTION: In subjecting an α,β-unsaturated carboxylic acid monomer or/ and its alkali metal salt, e.g., (meth)acrylic acid (sodium salt), to a W/O type reversed phase suspension polymerization in the presence of a crosslinking agent, e.g., ethylene glycol di(meth)acrylate; a high-molecular material having excellent water absorbability is prepared by using, as a dispersant, a carboxyl group-containing polymer having an affinity for organic solvents (e.g., n-hexane or xylene), e.g., a methacrylic acid/methyl methacrylate/2-ethylhexyl acrylate copolymer. This high-water-absorbing hydrogel is transparent, less colored and almost nontoxic and can be used in sanitary materials, agents for separating water from oil, dehydrating or drying agent, water retaining agent for soil, etc.
