Abstract

Using solution polymerization,a super water-absorbent resin with high suction speed and water absorbency was prepared.By using the acrylic acid and acrylamide as raw materials,N,N'-methylene-acrylamide as cross-linking agent,ammonium persulfate and hydrogen sulfite sodium as the initiator,and adding kaolin in the reaction of 60℃,the best conditions were determined.Water absorption was up to 819 g/g.
