  • Why is a targeted homopolymer polyacrylamide (PAM) a challenge?
  • The preparation of a targeted homopolymer polyacrylamide (PAM) or macroRAFT-PAM represented a substantive challenge due mainly to the long hydrocarbon-dodecyl alkyl in the activating group (Z) of the DDMAT which involves a high hydrophobicity of this latter in water.
  • What is copper-catalyzed controlled polymerization of acrylamide?
  • Copper-catalyzed controlled polymerization of acrylamide (AM) has always been a challenge, which typically exhibits low monomer conversion and broad molecular weight distribution (MWD) or requires complex/multistep reaction procedures, due to the highly active nature of the AM radical and its side reactions.
  • Does branched macroraft-Pam have a higher viscosity than Linear copolymers?
  • Here, we only reported the result of different branched copolymers obtained at a concentration of 10 wt%. The branched macroRAFT-PAM synthetized through a 10% mol of crosslinking agent exhibited a viscosity (ɳ = 0.72 Pa × s) thrice higher than its linear copolymer counterpart (ɳ = 0.22 Pa × s).
  • Why are hydrophobically water soluble associating (hwsap) polymers important?
  • Presently, the hydrophobically water soluble associating (co) polymers (HWSAP) continued to play an important role in the polymer industry due to their exceptional thickening properties in aqueous solution [ 1, 2, 3, 4, 5 ].
