production of starch-g-anionic polyacrylamide

  • Synthesis and application of amphoteric starch

    2009-9-5 · Anionic starch-graft-polyacrylamide (S-g-PAM) was prepared by alkaline hydrolysis. The hydrolytic agent (mixture of sodium carbonate and sodium hydroxide) was added to starch-graft-polyacrylamide emulsion, the concentration of the hydrolytic agent was 2.12 mol/L, and the molar ratio of sodium carbonate to sodium hydroxide was 1:1.
