Abstract

PURPOSE: To obtain a resin useful for a dehydrating agent, a water-retaining agent, etc., by a method wherein starch or cellulose and a water-solble polymeriable monomer are polymeried to obtain in a graft polymer and an aq. soln. or a water dispersion of the graft polymer is continuously introduced into a high-viscosity mixing reactor where the polymer is kneaded and crosslinked.
CONSTITUTION: Starch and/or cellulose, and a polymerizable monomer which is water-soluble or converted to a water-soluble monomer by htdrolysis, are polymerized in an aq. medium. The resulting graft polymer is subjected to hydrolysis to obtain an aq. soln. or a water dispersion of the graft polymer which is self-crosslinkable or can be crosslinked by using a crosslinker. When the polymer is self-crosslinkable, the aq. soln or the water dispersion of the polymer alone is continuously introduced into a cylinder-type high-viscosity mixing reactor where the polymer is kneaded and crosslinked to produce a water-insoluble, water-absorbing resin. When the polymer can be crosslinked by using a crosslinker, the aq. soln. or the water dispersion of the polymer together with the crosslinker is continuously introduced into the cylinder-type high-viscosity mixing reactor where the polymer is kneaded and crosslinked to produce a water-insoluble, water absorbing resin.
