  • How to synthesis high molecular weight branched polyacrylamide (PAM)?
  • The controlled synthesis of high molecular weight branched polyacrylamide (PAM) has been accomplished by using atomic transfer radical polymerization (ATRP) of acrylamide (AM) in water at room temperature. Halogen-functionalized aliphatic polyketones acted as macroinitiators in the polymerization.
  • 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.
  • 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).
  • How is polyacrylamide (PAM) a polymer with high molecular weight?
  • Polyacrylamide (PAM) with high molecular weight was synthesized by microemulsion method. Polyacrylamide was used as monomer, and a self-made initiator was used for polymerization under the condition of coexistence with sodium carbonate. The optimal polymerization parameters of PAM are determined: pH value of solution was 12. 3.
