Abstract

PURPOSE: To obtain the title bridged polymer with excellent absorbability, thickening property or the like useful as a paper diaper or the like by a method wherein an acrylic acid partial neutralized compound based on alkali metal salt is subjected to an aqueous polymerization in the presence of a water soluble polyhydric alcohol and the obtained water containing polymer is heated and dried.
CONSTITUTION: An acrylic acid partial neutralized compound 100 parts by wt. of which 60W90 mole % is present as an alkali metal salt such as sodium salt or the like is dissolved in water at a concentration of above 30wt% and 0.0005W20 parts by wt. of a water soluble polyhydric alcohol having two or more hydroxyl groups per a molecule capable of reacting carboxyl group such as diethyleneglycol, triethyleneglycol, glicerine or the like as well as a polymerization initiator are added and dissolved, thereafter subjected to an aqueous polymerization at a temperature of about 10W80°C. Subsequently, the obtained water containing polymer is dried by heating to carry out an esterifying reaction of a carboxyl group of a polymer and a hydroxyl group of a water soluble polyhydric alcohol and form a bridged structure. Thereby, an objective bridged polymer is obtained.
