Water absorbent having water-absorbent resin as main component, and method for producing same |
| abstract |
The present invention provides a production method capable of reducing the amount of residual monomer of a water-absorbent resin having a high specific surface area and reducing variations in the amount of residual monomer between water-absorbent resin particles. The production method of the present invention in sum is a method for producing a water absorbent having a water-absorbent resin as a main component, the method including a water-absorbent resin surface crosslinking step and a sulfur-containing reducing agent aqueous solution mixing step, wherein the (1) specific surface area of the water-absorbent resin, (2) average droplet diameter and temperature of the sulfur-containing reducing agent aqueous solution, (3) mixing conditions, and (4) heating and drying conditions are properly controlled. |
