METHOD FOR PRODUCING WHITE AND COLOR-STABLE WATER-ABSORBING POLYMER PARTICLES HAVING HIGH ABSORBENCY AND HIGH SALINE FLOW CONDUCTIVITY

摘要

The invention relates to a method for producing water-absorbing polymer particles. According to said method, a monomer solution or monomer suspension, containing at least one unsaturated carboxylic acid, at least one semicyclic ether of hydroquinone and at least one inorganic peroxide, is polymerized and the polymer particles are coated with at least one basic salt of a bivalent metal cation.
