Beschreibung
Zusammenfassung:	Provided is a method for producing water-absorbing resin particles suitable for use in absorbent goods and the like, the water-absorbing resin particles having exceptional water-absorbing performance, a suitable particle size, and a narrow particle-size distribution. A method for producing water-absorbing resin particles by inverse suspension polymerization of a water-soluble ethylenic unsaturated monomer in a carrier fluid, wherein the method for producing water-absorbing resin particles comprises conducting the inverse suspension polymerization reaction in the presence of an organic acid monoglyceride. 本发明提供种用于制造适用于吸收性物品等中的吸水性树脂粒子的方法，所述吸水性树脂粒子具有优异的吸水性能、合适的粒度和狭窄的粒度分布。种用于通过使水溶性烯键式不饱和单体在载体流体中反相悬浮聚合来制造吸水性树脂粒子的方法，其中用于制造吸水性树脂粒子的所述方法包括在有机酸甘油单酯的存在下进行反相悬浮聚合反应。
