  • Color-stable superabsorbent polymer composition
    Patent number: 7504551
    Abstract: A color-stable superabsorbent polymer having long-term color stability, and methods of manufacturing the polymer, are disclosed. The superabsorbent polymer is prepared using a sulfinic acid derivative, like 2-hydroxy-2-sulfinatoacetic acid, a salt thereof, or a mixture thereof, as the reducing agent in a polymerization initiator system for the preparation of a superabsorbent polymer from monomers. The resulting superabsorbent polymer resists color degradation during periods of extended storage, even at an elevated temperature and humidity.
