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.
