How Is Polyacrylamide Made?

Polyacrylamide gels are prepared by free radical polymerization of acrylamide and a comonomer crosslinker such as bis-acrylamide. Polymerization is initiated by ammonium persulfate (APS) with tetramethylethylenediamine (TEMED) as the catalyst (see figure below).

How is polyacrylamide gel made?

Polyacrylamide gels are made by chemical polymerization of a mixture of acrylamide and bisacrylamide (a cross-linker) in the presence of a catalyst and an initiator of the polymerization reaction.

Is polyacrylamide natural or synthetic?

polyacrylamide, an acrylic resin that has the unique property of being soluble in water. It is employed in the treatment of industrial and municipal wastewater. Polyacrylamide does not have the toxic effects of acrylamide monomer.
