Method for producing water-absorbent polymer particles having improved color stability |
| abstract |
The invention relates to a method for producing water-absorbent polymer particles, wherein at least one inorganic phosphoric acid and/or the salt thereof and at least one organic 2-hydroxy acid and/or the salt thereof are added, wherein the phosphorus in the inorganic phosphoric acid has an oxidation number of less than +V and the organic 2-hydroxy acid does not contain any ethylenically unsaturated groups, and to the water-absorbent polymer particles that can be obtained according to the method according to the invention. |
