Agglomerated superabsorbent polymer particles having a specific size ratio

Abstract:

Agglomerated superabsorbent polymer particles is provided and obtained by a method including the steps of (a) providing precursor superabsorbent polymer particles having a first mass average particle size .sup.1mAvPS, a first particle diameter ".sup.1D10" of not less than 30 .mu.m and a first particle diameter ".sup.1D90", (b) mixing the precursor superabsorbent polymer particles with a solution including polymerizable monomers and/or oligomers, or crosslinkable polymers, and (c) polymerizing the mixed solution if the solution includes polymerizable monomers and/or oligomers or crosslinking the mixed solution if the solution includes crosslinkable polymers. The agglomerated superabsorbent polymer particles have a second particle diameter ".sup.2D10" and a second particle diameter ".sup.2D90". The size ratio between the second particle diameter ".sup.2D90" and the first particle diameter ".sup.1D10" is determined by the following equation: << ##EQU00001##
