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, 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.
