  • How is acrylamide polymerized?
  • To achieve this, an acrylamide– bisacrylamide mix is polymerized (polyacrylamide) by the addition of ammonium persulfate (APS). The reaction, which is catalyzed by tetramethylethylenediamine (TEMED), forms a net like structure with pores through which analytes can move (Figure 2).
  • What causes autopolymerization of acrylamide?
  • Linear polyacrylamide — Contaminants with catalytic properties may cause what appears to be autopolymerization during the production, processing, or storage of marginally pure acrylamide. This results in the presence of linear polyacrylamide in the dry monomer.
  • How can we improve the production process of polyacrylamides?
  • With a close look at the manufacturing process of polyacrylamides, it is possible to identify the main CO 2 -emitting stages (drying, for instance) and work at improving the reaction and process efficiencies and the recovery of heat for further use, for example.
  • Does polyacrylamide depolymerize on acrylamide monomer?
  • Indeed, King et al. and Smith et al. confirmed the innocuity of polyacrylamide, whereas acrylamide monomer is classified as neurotoxic. In another study led on polyacrylamide used in agriculture, Anh et al. showed that polyacrylamide does not depolymerize on toxic acrylamide monomer, despite a misleading title .
