"Method of manufacturing stable color superabsorbent polymer particles, stable color superabsorbent particles, absorbent article, and diaper". a color stable superabsorbent polymer having long term color stability, and methods for manufacturing the polymer are exposed. The color stable superabsorbent polymer is prepared, essentially in the absence of a persulphate, and is subjected to a low dose of ultraviolet radiation. The resulting superabsorbent polymer resists color degradation during extended storage periods, even at elevated temperatures and humidity. |
