摘要：

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 (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 below:$\begin{array}{cc}\mathrm{Rxl}={\left(\frac{\left(\frac{1}{\mathrm{rho\_dry}}+\frac{\mathrm{x\_L}}{\mathrm{rho\_liq}}\right)}{N_A·\sum _i\frac{{\mathrm{w\_xl}}_i}{{\mathrm{Mr\_CSL}}_i}}\right)}^{\frac{1}{3}}& \left(I\right)\end{array}$
