The Preparation of High Polymer Absorbent Resin

Abstract

Under the aerobic condition, using tap water as solvent, the super absorbent resin was synthesized by solution polymerization of acrylic acid-sodium acrylate, The result showed the water absorbency of last production in tap water was 578g/g, when the concentration of monomer was 25%, the neutralization degree of monomer was 80%, the amount of initiator and crosslinking agent was 0.15% and 0.07% respective, the react temperature was 90°C and the time of reaction was four hours. the crosslinking action of crosslinking agent was not influenced, although tap water was used as solvent. Which will has important directive significance to the large-scale industrial production of high polymer absorbent resin.
