  • Can polyacrylamide be a drag reducer?
  • A very simple cationic monomer and a cationic hydrophobically associating polyacrylamide were synthesized, and the polymer was to function as a drag reducer. The structures of monomer and polymer were characterized by IR and NMR, and the drag-reducing rate, below and above the critical association concentration, (CAC) was tested.
  • Why is polyacrylamide not a polyamide?
  • It can be viewed as polyethylene with amide substituents on alternating carbons. Unlike various nylons, polyacrylamide is not a polyamide because the amide groups are not in the polymer backbone. Owing to the presence of the amide (CONH 2) groups, alternating carbon atoms in the backbone are stereogenic (colloquially: chiral).
  • Is polyacrylamide a hydrophobically associating polymer?
  • The structures of monomer and polymer were characterized by IR and NMR, and the drag-reducing rate, below and above the critical association concentration, (CAC) was tested. The modified polyacrylamide is a typical hydrophobically associating polymer, reaching a CAC at a mass concentration of about 0.25% (by weight).
  • Is polyacrylamide a polyolefin?
  • Polyacrylamide is a polyolefin. It can be viewed as polyethylene with amide substituents on alternating carbons. Unlike various nylons, polyacrylamide is not a polyamide because the amide groups are not in the polymer backbone.
