METHOD FOR PRODUCING WATER-ABSORBING POLYMER PARTICLES BY SUSPENSION POLYMERIZATION

摘要

The invention relates to a method for producing water-absorbing polymer particles by suspension polymerization and thermal surface post-crosslinking, the agglomerated base polymer obtained by the suspension polymerization having a centrifuge retention capacity of less than 37 g/g and the thermal surface post-crosslinking proceeding at 140 to 220°C.
