Study on synthesis craft of potato starch salt-resisting super absorbent polymer
摘要
Abstract
Without the protection of nitrogen gas, with the materials of potato starch, acrylic acid and acrylamide,ammonium persulfate as initiator with glycerol as crosslinking agent,salt-resisting super absorbent polymers was prepared by aqueous solution polymerization method, and synthesis craft of potato starch salt-resisting super absorbent polymer was optimized. The results were as follows: when mass ratios of starch to monomer was 1:7,mole ratio AA to AM was 0.5:1, degree of neutralization was 70%, reaction temperature was 60℃, the amounts of initiator, crosslinking agent were 0.25 % ,0.6% ( based on the amount of monomers), respectively, cross-linking time was 1.5h. Under this condition,absorption power in 0.9% NaCl was 76g/g, and distilled water absorption of super absorbent polymer was 786g/g.关键词
