Abstract: The invention relates to water-absorbent polymers for producing flame-retardant compositions, containing at least one ethylenically unsaturated monomer that has been incorporated by polymerisation and contains acidic groups. The acidic groups are present as 51 to 64 molar % carboxylate groups and the carboxylate groups at least partially comprise potassium ions as counterions. The invention also relates to a method for producing the water-absorbent polymers and to the production of flame-retardant compositions and coatings.
