<p>A color-stable superabsorbent polymer having long-term color stability, and methods of manufacturing the polymer, are disclosed. The color-stable superabsorbent polymer is prepared in the essential absence of a persulfate, and is subjected to a low dose of ultraviolet radiation. The resulting superabsorbent polymer resists color degradation during periods of extended storage, even at an elevated temperature and humidity.</p> |
