Particle-shaped water absorbing agent and method for producing the same |
| abstract |
The present invention provides a particle-shaped water absorbing agent, which comprises a polyacrylic acid and/or a salt thereof in a range of 70 to 99.9% by weight to the particle-shaped water absorbing agent, a polyalkyleneglycol, and iron by iron content in a range of 0.001 to 5 ppm by weight. The invention also provides a method for producing the particle-shaped water absorbing agent. In a method for producing a water absorbing resin including the steps of polymerizing an unsaturated-monomer aqueous solution containing an acrylic acid and/or a salt thereof in a range of 70 to 100 mol% and drying a hydrous gel polymer, the unsaturated-monomer aqueous solution containing N-oxyl compound by 0.01 to 10 ppm by weight based on an unsaturated monomer is polymerized. The particle-shaped water absorbing agent obtained by the method of the invention satisfies both properties of the excellent water-absorbing property and improved whiteness of the surface color of particles. |
