Abstract

PURPOSE: To produce title crosslinked product having a high initial absorption rate for aqueous solutions which is useful as physiological cotton or the like, by polymerizing, in an aqueous solution, a partially neutralized acrylic acid in the presence of a water-soluble polyhydric alcohol and a surfactant, and heat-drying the moist polymer obtained.
CONSTITUTION: 100pts.wt. of a partially neutralized acrylic acid in which 60W 90mol% is in the form of alkali metal salt is dissolved in water to make up an aqueous solution of a concentration of at least 30wt%. To the solution there are added 0.0005W20pts.wt. of a water-soluble polyhydric alcohol, such as diethylene glycol, triethylene glycol, polyethylene glycol, glycerin or triethanolamine, and 0.01W10pts.wt. of a water-soluble and/or-dispersible surfactant. The resulting solution, then, is subjected to solution polymerization. The moist polymer obtained is heat-dried to obtain title crosslinked product.
