Method for producing white and color-stable water-absorbing polymer particles having high absorbency and high saline flow conductivity |
摘要 |
Water-absorbing polymeric particles are produced by polymerizing a monomer solution or suspension comprising at least one unsaturated carboxylic acid and at least one hydroquinone monoether, and coating the polymeric particles with at least one salt of a tervalent metal cation of a carboxylic acid and/or at least one basic salt of a tervalent metal cation. |
