Abstract

In this paper, MBA was used as crosslinker, SiO₂ and carboxymethyl cellulose as the nucleus-maker, nucleus-cell style SAP was synthesized by AA-AM-AMPS three-member copolymerization. The multiple of water-absorbent by SAP could reach 1150 times by the optimization of the technological conditions. Nucleus-cell style SAP has a good command of fluidity and wet-resistance, it can keep its fluidity 15 hrs after exposure under the air with the humidity of 84%. The best proportion of AA, AM, AMPS is 13:3:4, and the best content of SiO₂ is 0.8%.
