- 摘要：
PROBLEM TO BE SOLVED: To provide a production method of a water-absorbing resin particle which shows a high water-retention capacity and a high water-absorption power under load, is excellent in water-absorbing rate, has a low water-soluble content and can be suitably used for a hygienic material, the water-absorbing resin particle obtained thereby and the hygienic material using the same.
SOLUTION: The production method of the water-absorbing resin particle is a method for producing a water-absorbing resin by polymerizing a water-soluble ethylenically unsaturated monomer. Here, after performing polymerization using a water-soluble azo radical polymerization initiator in the presence of a polyvalent glycidyl compound as an internal crosslinking agent, the obtained water-absorbing resin is subjected to post-crosslinking with a post-crosslinking agent.
