Abstract:
1. A water-absorbing, antimicrobial polymer particle comprising: from about 1 to about 500 ppm, based on the polymer particle, of a silver ion based on a silver salt Ag at least about 10 wt. %, based on the polymer particle, of a water-absorbing polymer based on: wherein the concentration of the silver ion based on a silver salt in at most about 90 vol. % of the water-absorbing, antimicrobial polymer particle is less than about 0.01 ppm and wherein the water-absorbing, antimicrobial polymer particle is post-crosslinked with a post-crosslinker in a quantity within a range of from about 0.01 to about 30 wt. %, based on the weight of the polymer particle.
