Abstract

A method for making water-absorbing polymer particles is provided and includes a first aqueous polymerization solution including crosslinkers, polymerizable monomers and/or oligomers and inorganic solid particles, and a second aqueous solution including inorganic solid particles, crosslinkers and either polymerizable monomers and/or oligomers, or crosslinkable polymers. The average closest distance between two neighboring crosslinkers (R) from the first aqueous polymerization solution or from the second aqueous solution for a specific X-load of the water-absorbing polymer particle is calculated via the formula below:
