  • What is the maximum amount absorbed by polyacrylamide (C HPAM)?
  • The solubility test results confirmed the maximum amount absorbed by polyacrylamide ( [C HPAM] = 66.42 g/L) in order to avoid aggregation, gelification, and enhance the drilling mud by utilizing the prescribed contents. 1. Introduction Currently, water-soluble polymers are very important for many industrial applications [ 1, 2 ].
  • Does polyacrylamide hydrolyze under acidic conditions?
  • As reported by Muller et al., polyacrylamides undergo hydrolysis under acidic conditions to yield poly (acrylamide-co-acrylic acid). Amide groups will completely hydrolyze under conditions of appropriately low pH, and polymer weight will remain relatively stable during hydrolysis, as the following formula , , .
  • Does cross-linker increase viscosity of polyacrylamide?
  • It has been noted that an increase in the viscosity is due to the cross-linked feature of polyacrylamide. Cross-linker significantly increases the viscosity of linear gel by increasing the molecular weight of the base polymer by linking multiple molecules together. Cross-linker increases molecular weight without additional polymers.
  • Why are cross-linked variants of polyacrylamide more stable?
  • Cross-linked variants of polyacrylamide have shown greater resistance to degradation. Hence, they are more stable for longer periods. Therefore, linking of polymer chains through chemical linkages gives material a more rigid structure and potentially a better-defined shape [ 45 ]. 3.8. Solubility Test
