摘要:
A method includes the steps of: adding an organic surface cross-linking agent to a water absorbent resin having a cross-linked structure; adding a liquid permeability improving agent to the water absorbent resin concurrently with or after the addition of the organic surface cross-linking agent; and then adding a lubrication improving agent to the water absorbent resin. This provides a particulate water absorbing agent and a method for producing it, the particulate water absorbing agent being suitable for pneumatic transportation, suffering no decrease in the effect of the liquid permeability improving agent, and excelling in properties such as fluidity and damage resistance after the pneumatic transportation.
