  • Does glyoxal and polyacrylamide have a gel phase?
  • The mixture of polyacrylamide and glyoxal presents always as sol at low polymer concentration ( C<C ∗ ), irrespective of the glyoxal concentration is. A gel phase appears at a polymer concentration superior to C ∗.
  • What happens when polyacrylamide and glyoxal are mixed?
  • When the solutions of polyacrylamide and glyoxal are mixed, a gelation may occur. Table 1 illustrates the determination of the state of simple sol or gel by means of viscosity measurement. The concentration was fixed at 2 g/l, which is superior to C ∗. As we can see, the viscosity of the polymer varies with the concentration in glyoxal.
  • Can nonionic polyacrylamide be used as a gel fracturing fluid?
  • Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.
  • What is the composition of polyacrylamide gels?
  • The composition of polyacrylamide gels is generally expressed in terms of T (the total acrylamide and Bis monomer concentration in g/100 ml) and C (the percentage of cross-linker in the total amount of acrylamide).
