  • How is anionic starch-graft-polyacrylamide (S-G-Pam) prepared?
  • 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.
  • What are the different types of anionic polyacrylamide synthesis technologies?
  • The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.
  • What is starch-G-poly acry1amide-co-acrylic acid?
  • Starch-g-poly(acry1amide-co-acrylic acid) copolymers have potential use as flocculants and a structural similarity to saponified starch-g-polyacrylonitrile, which functions as both a thickener for aqueous systems2 and as an absorbent for water.3 Unmodified Globe corn starch was from CPC International and contained 10-14% HzO.
  • How to obtain stable emulsion of amphoteric starch-graft-polyacrylamide as flocculant?
  • 4. Conclusions A stable emulsion of amphoteric starch-graft-polyacrylamide as flocculant was obtained by inverse emulsion polymerization, hydrolysis reaction and Mannich reaction subsequently. In hydrolysis reaction, both NaOH and Na 2 CO 3 were common hydrolyzing agents.
