Abstract

PURPOSE: To obtain the absorbing agent having high water retention property even under a pressurized condition by a method wherein an acrilic acid type monomer and a crosslinkable monomer are copolymerized in the presence of a surface active agent and, thereafter, the resulting copolymer is converted to a crosslinked poly (alkali metal acrylate) by heating and drying.
CONSTITUTION: In the presence of the surface active agent such as a water soluble and/or a water dispersible polyoxyethylene alkylether, 100pts.wt. of the acrylate type monomer comprising 0W50mol% of acrylic acid and 50W100mol% of an alkali metal acrylate and 0.001W5pts.wt. of the crosslinkable monomer such as ethylene glycol diacrylate are mixed. the resulting mixture is subjected to solution copolymerization in water at a concn. of 25wt% or more to form a gel like water containing polymer and, moreover, said polymer is heated and dried to obtain the crosslinked poly(alkali metal acrylate) used as the absorbing agent. This absorbing agent shows high absorbing capacity when contacted with an aqueous substance and maintains water retention property even under a pressurized condition.
