Absorbent articles comprising superabsorbent polymer particles having a non-covalently bonded surface coating

The present invention relates to absorbent articles comprising superabsorbent polymer particles. The superabsorbent polymer particles are coated with cationic polymers having 1 to 25 mol/kg, referring to the total weight of the cationic polymers, of cationic groups, which can be protonated. The cati...

More Information
Summary:The present invention relates to absorbent articles comprising superabsorbent polymer particles. The superabsorbent polymer particles are coated with cationic polymers having 1 to 25 mol/kg, referring to the total weight of the cationic polymers, of cationic groups, which can be protonated. The cationic polymers are not substantially covalently bound to the superabsorbnet polymer particles. Furthermore, the superabsorbent polymer particles are not substantially covalently surface cross-linked.
