PROCÉDÉ DE FABRICATION DE PARTICULES POLYMÈRES ABSORBANT L'EAU AYANT DES ZONES AVEC DES PARTICULES SOLIDES INORGANIQUES ET DES ZONES SENSIBLEMENT EXEMPTES DE PARTICULES SOLIDES INORGANIQUES
A method for making water-absorbing polymer particles is provided and consists of a first aqueous polymerization solution comprising crosslinkers, polymerizable monomers and/or oligomers and inorganic solid particles, and a second aqueous solution comprising inorganic solid particles, crosslinkers and either polymerizable monomers and/or oligomers, or crosslinkable polymers. The average closest distance between two neighboring crosslinkers (RXL) 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 (I)
