Preparation of fast superabsorbents with enhanced elastic behavior

The invention relates to a method for producing water-absorbing polymers, so-called superabsorbents. The present invention is based on the discovery that extrusion of hydrogels via an orifice plate (13) following complex design rules reduces the negative effects of thixotropy and increases the absor...

Beschreibung
Zusammenfassung:	The invention relates to a method for producing water-absorbing polymers, so-called superabsorbents. The present invention is based on the discovery that extrusion of hydrogels via an orifice plate (13) following complex design rules reduces the negative effects of thixotropy and increases the absorption rate of superabsorbents made from hydrogels. 本发明涉及一种制备吸水聚合物，所谓的超吸收剂的方法。本发明基于以下发现：经由遵循复杂设计规则的孔板(13)挤出水凝胶降低了触变性的负面影响并提高了由水凝胶制成的超吸收剂的吸收速度。
