AGGLOMERATED SUPERABSORBENT POLYMER PARTICLES |
| 摘要 |
The present invention relates to agglomerated superabsorbent polymer particles which have been agglomerated by using a multivalent salt having a valence of three or higher. Due to agglomeration, the mean average particle size increase by at least 25% compared to the mean average particle size of the non-agglomerates superabsorbent polymer particles. |

1. Agglomerated superabsorbent polymer particles obtained by a method comprising the steps of:
a) providing superabsorbent polymer particles having a first mass average particle size; b) mixing the superabsorbent polymer particles with a solution comprising water and a multi-valent salt having a valence of three or higher; wherein the agglomerated superabsorbent polymer particles have a second average particle size which is at least 25% greater than the first mass average particle size. |
