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.
L'invention concerne des polymères hydroabsorbants pour produire des compositions ignifugeantes, comportant au moins un monomère éthyléniquement insaturé, incorporé par polymérisation, qui comporte des groupes acides. Selon l'invention, ces groupes acides sont représentés entre 51 et 64 % mol. par des groupes carboxylate, et ces groupes carboxylate comportent au moins partiellement des ions potassium en tant que contre-ions. Cette invention se rapporte en outre à un procédé de production de ces polymères hydroabsorbants, ainsi qu'à la production de compositions ignifugeantes et de revêtements ignifugeants.
