Polyacrylamide is a type of water-soluble linear high molecular polymer made by free radical polymerization of acrylamide (AM) monomer. It has excellent flocculation property and can reduce the frictional resistance between liquids. There are four types of PAM, including nonionic, anionic, cationic, and more.

A CATIONIC POLYACRYLAMIDE DISPERSION SYNTHESIS BY DISPERSION

In the present work, A cationic polyacrylamide (PAM) emulsion was synthesized from acrylamide (AM) and a cationic monomer, acryloyloxyethyltrimethyl ammonium chloride (DAC), using the dispersion polymerization method in aqueous ammonium sulfate ((NH4)2SO4) solution. The polymerization was initiated by tert-butyl hydroper-

Anionic Poly-Acrylamide (aPAM)

ANIONIC POLYACRYLAMIDE. Composition: Negatively charged copolymers of acrylamide are widely used as retention aids and dry-strength resins. However, different molecular mass ranges are used for these two roles. Anionic acrylamide copolymer retention aids typically have molecular masses in the range of 5 to 20 million grams per mole.

The difference of anionic, cationic and Non-ionic polyacrylamide

Polyacrylamide is not the only acrylamide unit, the acrylamide unit is mostly called polyacrylamide. Thus, polyacrylamide may contain structural units that can be ionized or hydrolyzed in water to carry charges. As a result, there are cationic, anionic, non-ionic, amphoteric ion type of various polyacrylamide anionic polyacrylamide 。
