  • How was high molecular weight poly (acrylamide) synthesized?
  • High molecular weight poly (acrylamide) (PAM) samples were synthesized using our solution polymerization technique. The reaction was initiated using thermal initiators potassium and ammonium persulphate (KPS and APS), and redox system comprising APS-TMEDA or N,N,N',N'-tetramethylethylenediamine.
  • What is high molecular weight polyacrylamide (PAM)?
  • Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
  • How are high molecular weight polyacrylamide nanoparticles prepared?
  • High molecular weight polyacrylamide nanoparticles were prepared by inverse-emulsion polymerization of aqueous acrylamide solution in xylene as a continuous phase under various conditions in the presence of a mixture of non-ionic emulsifiers (Tween 85 and Span 80).
  • What is P olyacrylamide (Pam) & its copolymers?
  • P olyacrylamide (PAM) and its copolymers are of important polymeric materials in petroleum industry, for example in drilling fluids and enhanced oil recovery. High molecular weights of these polymers are needed to have optimum efficiency in the above given applications.
