Study on Synthesis and Properties of a Starch-Polyacrylamide Graft Copolymer by HRP

Abstract:

A starch-polyacrylamide graft copolymer has been synthesized in water by means of horseradish peroxidase (HRP)/H₂O₂/acetylacetone (ACAC). It is discussed through single factor experiment that the effects of system pH, reaction temperature and amount of HRP on the residual acrylamide (AAM) content. The results show that the ideal copolymer was synthesized when mass ratio of starch and AAM was 2:1, and catalyst was HRP/H₂O₂ at 30 °C for 3.5 h. The residual AAM content was about 1.0%. The structure and properties of the graft copolymer are characterized by FTIR, NMR. The graft copolymer is used as retannage.
