Anionic polyacrylamide (APAM) series products are water-soluble linear polymers synthesized under high degree polymerization, easily soluble in water, almost insoluble in the benzene, the ether, the aliphatics, the acetone and other common organic solvents. At the meantime, APAM series products also have valuable properties like the flocculation, the thickening, the shear property, the drag-reduction and the dispersibility etc., thus widely used in the oil recovery, the mineral processing
Polyacrylamide and acrylamide in flocculation processes and potential environmental 55 hazards 56 The word polyacrylamide and the acronym “PAM” (for polyacrylamide) refer to a group of water 57 soluble molecules formed by polymerization of acrylamide monomers. PAMs have been used for
