Production method for polyacrylic acid (polyacrylate) water-absorptive resin |
| abstract |
Provided is a method for manufacturing an absorbent resin which avoids the problems associated with the addition of particulate additives and fine water absorbent resin, and which can stably and efficiently obtain a highly water absorbent resin. A process for producing an aqueous monomer solution for producing an aqueous solution containing a monomer mainly composed of acrylic acid (salt); A polymerization step of polymerizing the monomer to obtain a hydrogel crosslinked polymer; And a drying step of drying the hydrogel crosslinked polymer to obtain a dried polymer, wherein the adding step of adding the particulate additive to the monomer aqueous solution and / or the hydrogel crosslinked polymer Wherein the concentration of oxygen in the ambient atmosphere of the particulate additive is 5 vol% or less in the adding step. |
