Preparation and Properties of Anti-Salt Super Absorbent Resin

Abstract:

The maleic acid ( MA ) 2-acrylamido-2-methylpropanesulfonic acid (AMPS) and acrylamide (PAMPS/AM/MA) superabsorbent copolymer was synthesized by aqueous solution polymerization with ammonium persulfate as initiator,N,N-methylene-bisacrylamide ( NMBA) as crosslinking agent. The influence of neutralization degree of MA,mass ratio of AMPS to acrylamide ( AM) ,the amount of crosslinking agent and initiator,and reaction temperature on the absorption capability of water and salt solution were investigated. The results show that the water absorbency of the superabsorbent polymer prepared at the optimum condition in deionized water and in 0.9% NaCl solution is about 235 and 132g/g,respectively,and under the same conditions,the sample has more excellent water absorption and salt-resistance.
