Open publisher page 0 citations

Abstract

Using(NH4)2S2O8/CO(NH2)2 initiation system, the modified starch was synthesized by the graft copolymerization of starch with DMDAAC. The optimum conditions of graft copolymerization are determined. Ratio of starch and monomer is 1∶9, initiator concentration is 0.33 mmol/L-1 , monomer ratio of AM∶DMDAAC is 12∶1,reaction time is 5 h, reaction temperature is 40 ℃. The structure of the copolymer was confirmed by FTIR.
