Polyacrylamide classification

Classification of polyacrylamide: anionic, cationic, nonionic, zwitterionic.

Polyacrylamide (PAM), which is polymerized from acrylamide monomers. The monomer acrylamide is very chemically active. A series of chemical reactions can be carried out at the double bond and the amide group. Different processes can be used to introduce different functional groups to obtain different charge products: anionic, cationic, nonionic, and bisexual. Ionic polyacrylamide

Polyacrylamide (PAM), which is polymerized from acrylamide monomers. The monomer acrylamide is very chemically active. A series of chemical reactions can be carried out at the double bond and the amide group. Different processes can be used to introduce different functional groups to obtain different charge products: anionic, cationic, nonionic, and bisexual. Ionic polyacrylamide. The appearance of the product is white powder, soluble in water, almost insoluble in benzene, ether, ester, acetone and other general organic solvents. Its aqueous solution is almost viscous liquid. It is non-dangerous, non-toxic, non-corrosive, solid. PAM is hygroscopic, hygroscopicity increases with the increase of ionicity, PAM has good thermal stability; when heated to 100 °C, it has excellent stability, but when it is above 150 °C, it is easy to differentiate and produce nitrogen, and imidization occurs between molecules. Do not dissolve in water, density (g) ml 23 ° C 1.302. The vitrification humidity is 153 ° C, and PAM exhibits non-Newtonian fluidity under stress.
