Abstract

PURPOSE: To prepare title polymer, which is insoluble in water, excellent in water absorption properties, and not sticky after water absorption, by reacting a polysaccharide with acrylic acid (a water-soluble derivative) in the presence of an oil- soluble nonionic surfactant and a water-soluble polymerization initiator, in a specified reaction medium.
CONSTITUTION: A petroleum hydrocarbon solvent (A) such as benzene or n- hexane, of boiling point at least 5°C higher than the polymerization temperature and not higher than 100°C, containing a polysaccharide such as starch or cellulose and an oil-soluble nonionic surfactant having a lipophilic group, is mixed with an aqueous solution (B) containing at least 35wt%, particularly 40W50wt%, of acrylic acid (a water-soluble derivative) and a water-soluble polymerization initialor, in such a ratio that the mol ratio of acrylic acid (the derivative) to a hexose unit in the polysaccharide, is 5W60, and the volume ratio of it to the hydrocarbon solvent, is 1/1W1/5, and the mixture is reacted at 30W100°C for 2W10hr, to obtaine a water- absorbing graft polymer, having the polysaccharide as the backbone polymer and acrylic acid (the derivative) as the branch polymer.
