PROCESS FOR PRODUCING SUPERABSORBENT POLYMER PARTICLES

The invention relates to a process for producing superabsorbent polymer particles, comprising polymerization of a monomer solution, drying the resulting polymer gel and grinding the dried polymer gel with a roll mill, wherein the rolls of the roll mill are cleaned by reducing the feed rate to the ro...
