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 1mAvPS, a first particle diameter “1D10” of not less than 30 μm and a first particle diameter “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 “2D10” and a second particle diameter “2D90”. The size ratio between the second particle diameter “2D90” and the first particle diameter “1D10” is determined by the following equation: 7
