摘要
A process for producing water-absorbing polymer particles with low caking tendency and high absorption under pressure, comprising polymerization of a monomer solution or suspension, drying of the resulting polymer gel, grinding, classifying, thermal surface postcrosslinking and coating with silicon dioxide, wherein the water-absorbing polymer particles have been coated, before, during or after the surface postcrosslinking with aluminum cations.
