Abstract
A kind of high-performance water-absorbent resin had been successfully synthesized by a simple method using potassium pesulfate as initiator,N,N'-Methylenebisacrylamide as crosslinker,and starch,acrylamide and acrylic acid as raw materials reaction in aqueous solution.The results indicated that when the dosage of monomer was 12g,reaction temperature was 30℃,reaction time was 2h,the neutralization of acrylic acid was 94%,the initiator was 0.02g,and crosslinker was 0.0015g,the high-performance water-absorbent resin could be obtained.The suction water ratio of the product in distilled water could be reached 699.99g/g.
