Abstract

PURPOSE: To produce the titled resin which is water-insoluble and can absorb water in an amount several hundred times its own weight, by copolymerizing a specified vinyl monomer with acrylamide in the presence of a water-miscible or water-soluble divinyl compound.
CONSTITUTION: A low-moisture, porous, cationic highly waterabsorptive resin is prepared by dissolving (A) 25W100mol% vinyl monomer containing a tert. or quat. amino group, (e.g., dimethylaminoethyl (meth)acrylate), (B) 75W0% acrylamide and (C) 0.005W0.1pt.wt. (per 100pts.wt. total monomer) water-miscible or water-soluble divinyl compound (e.g., N,N-methylenebis(meth)acrylamide), adjusting the solution to a pH of 3W7, subjecting the solution to a copolymerization reaction in the presence of an initiator such as a redox type or an azo type, and evaporating the moisture by the heat of polymerization.
