Polyacrylamide, also briefly referred as PAM, is commonly a polymer with acrylamide monomers bonded connected by end to end configuration; it is a hard glassy solid at room temperature. Because of the difference in production methods, the products can be white powder, translucent beads and flaky like. Its density is 1.302 g/cm3 (23 ??C) with glass transition temperature being 153 ??C and softening temperature being 210 ??C. It has good thermal stability and is soluble in water; its aqueous solution is clear and transparent with its viscosity increasing with increased molecular weight of the polymer, and also having a logarithmic relationship with the change in concentration of the polymer. Except for a few solvent such as acetic acid, acrylic acid, ethylene glycol, glycerol and formamide, it is generally insoluble in organic solvents.
