  • What is polyacrylamide synthesis?
  • The synthesis of polyacrylamide typically involves the polymerization of acrylamide (C 3 H 5 NO) monomers, often through a free radical mechanism. The resulting long chains can be crosslinked to form a gel, or left linear to create a variety of forms. Several properties make polyacrylamide a crucial compound in various applications.
  • Why is polyacrylamide a versatile polymer?
  • Versatility: The physical properties of PAM can be altered by changing the polymerisation process. This means that by varying the degree of polymerisation or crosslinking, PAM can be tailored to specific needs, resulting in diverse forms and uses. Polyacrylamide has found extensive use in several sectors due to its unique properties.
  • What is polyacrylamide (PAM)?
  • Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 × 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007).
  • Can polyacrylamide contribute to residual polymer formation?
  • Common methods for treating PAM are membrane filtration 25, thermal distillation 24, oxidation treatment 26, and biological treatments 27. However, addressing the challenge posed by PAM remains a pressing issue within the industry. Fig. 1: Polyacrylamide and its fragments may contribute to residual polymer formation.
