Abstract
PURPOSE:To improve workability in handing of hydrous (meth) acrylic cationinc highly water absorptive resin by transforming the resin to a liquid form by dispersing fine particles of the resin in aq. soln. of polyvalent anionic salt of sulfate or phosphate, etc. CONSTITUTION:(Meth) acrylic cationic polymer is dispersed in aq. soln. of polyvalent anionic salt of sulfate such as ammonium sulfate, or phosphate such as sodium phosphate, etc. Using the aq. dispersion of the salt as starting material, the salt is crosslinked by adding about 10-90mol.% (meth) acrylamide as functional group and about 0.002-5mol.% formaldehyde etc., as crosslinking agent, at <=3pH and 50-70 deg.C. Thus, liquid dispersion of fine particles of high water-absorptive resin having about 100mum particle size is obtd. Moreover, separation of resin particles due to sedimentation or floating up is also prevented by the effect of coexisting polyvalent anionic salt for retarding swelling of the resin particles and by adjusting the specific gravity of the liquid.
