PAM polyacrylamide is made of acrylamide (AM) monomer by free radical polymerization of water-soluble linear polymer, has good flocculation, can reduce the friction resistance between the liquid, according to the ionic characteristics can be divided into non ion, anion, cation and amphoteric type four types. Polyacrylamide (PAM) is insoluble in most organic solvents, such as methanol, ethanol, acetone, ether, aliphatic hydrocarbons and aromatic hydrocarbons, with the exceptio...
