    摘要： 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.

    摘要： A process for the preparation of superabsorbent polymer containing clay, the process including the steps of (I) polymerizing a polymerization mixture comprising: (a) one or more ethylenically unsaturated carboxyl-containing monomers, (b) one or more crosslinking agents, (c) optionally one or more comonomers copolymerizable with the carboxyl-containing monomer, (d) neutralizing agent to partially neutralize the polymer to from about 50% to about 99%, by weight, and (e) a polymerization medium, to form a crosslinked partially neutralized hydrogel, (II) admixing a clay with the crosslinked partially neutralized hydrogel to form partially neutralized superabsorbent polymer-clay hydrogel; (III) drying the crosslinked partially neutralized hydrogel at a temperature from about 190° C. to about 210° C. and for a time period of from about 15 minutes to about 120 minutes, and (IV) comminuting the dried partially neutralized superabsorbent polymer-clay hydrogel to particles.
