Method for producing a water-absorbing polymer particles in the white and color stability with a high absorption performance 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, at least one hydroquinone monoether and at least one inorganic peroxide and coating the polymeric particles with at least one basic salt of a bivalent metal cation.
