  • What are cross-linked starch and starch-G-polyacrylamide materials?
  • Cross-linked potato starch (StMBA) and starch-g-polyacrylamide materials with a high content of natural polymer from 60 to 90 wt.% (St60–St90) were synthesized by double chemical-chemical modification (grafting and cross-linking). Eco-friendly starch absorbents were tested for removal of Cu 2+ and Fe 3+ from aqueous solutions.
  • How are cross-linked acrylamide starch copolymers synthesized?
  • The cross-linked acrylamide starch copolymers were synthesized by free radical initiated polymerization of potato starch (St, 2.28 g) with acrylamide (AM content from 10 to 40 wt.% on the starch weight).
  • What is graft copolymerisation of starch with acrylamide and methylpropanesulfoacid?
  • A copolymer was synthesised by graft copolymerisation of starch with acrylamide and 2-acrylamido-2-methylpropanesulfoacid for oil recovery enhancement . When using 0.2 % of the grafted starch [S-g-P (AM- co -AMPS)] as the flooding agent, a higher enhanced oil recovery rate was obtained than with hydrolytic polyacrylamide (HPAM).
  • What is a starch graft-polyacrylonitrile polymer?
  • Mostly, they are cross-linked copolymer of acrylates and acrylic acid and grafted starch–acrylic acid polymer that are prepared by reverse suspension and emulsion polymerisation, aqueous solution polymerisation and starch graft polymerisation. Alkaline hydrolysis of starch-graft-polyacrylonitrile (SPAN) led to the first commercial SAP.
