Abstract:
A process for producing odor-inhibiting water-absorbing polymer particles based on ethylenically unsaturated monomers bearing acid groups, wherein the acid groups have been neutralized to an extent of from 40 to 70 mol % and the polymer particles are coated with a condensed tannin and/or a hydrolyzable tannin.
