| Abstract: | The salt-tolerant super absorbent resin was synthesized by aqueous solution polymerization with starch,acrylic acid（AA） and acrylamide（AM） as raw material.The influences of starch,ratio of AM to AA,neutralization of acrylic acid,initiator and crosslinking agent were investigated on water absorption of the resin.The optimal polymerization conditions were obtained when reaction temperature was 50 ℃,the mass fraction of starch,acrylamide,initiator and crosslinking agent was 15 %,40 %,2.4 % and 0.03 % respectively in acrylic acid.The highest absorbencies of prepared composites for distilled water and saline water were 612 g/g and 147 g/g,respectively. |
