Abstract�� Using potato starch and AA as raw material,K2S2O8 as initiator and AlCl3 as crosslinker,starch-based superabsorbent polymer were synthesized by aqueous solution polymerization.Reasonable re-action time,absorbency velocity,repeated swelling properties and water conservation performance of pol-ymer were determined.The results showed that,when amount of ��(K2S2O8) = 0.15%,��(AlCl3) = 0.1%,m(AA) �� m(starch) = 6�� 1,neutralization degree of acrylic acid was 70% and reaction for 80 min at 60 ��,the distilled water absorbency of SAP was 1 235 g /g,and 0.9% NaCl water solution ab-sorbency of SAP was 101 g /g at a faster rate of water absorption.The synthesized SAP possess the capa-bility of water reabsorption and water retention.FTIR proved the structure of SAP to be graft copolymer of starch and acrylic acid(Na),X-ray diffraction peaks of SAP showed dispersing diffraction featmes.TG and DTA analyses explained the good thermal stability of SAP.
