Abstract:
1. Polymeric particles capable of absorbing blood and or body fluids comprising a) at least one interpolymerized ethylenically unsaturated acid-functional monomer, b) at least one interpolymerized crosslinker, c) optionally one or more interpolymerized ethylenically and/or allylically unsaturated monomers copolymerizable with a), d) optionally one or more water-soluble polymers onto which said monomers a), b), and optionally c) are at least partially grafted, and e) optionally one or more reacted postcrosslinkers, wherein said polymeric particles are coated with at least one surfactant and with at least one solvent of the general formula (I) wherein R R n is an integer from 1 to 5, wherein the polymer particles are further coated with aluminum cations.
