    Polyacrylamide PAM, with the chemical formula of (C3H5NO)n and the CAS NO. of 9003-05-8, is a linear polymer. Polyacrylamide polymer has good thermal stability, can be dissolved in water in any proportion, and the aqueous solution is a uniform and transparent liquid. PAM is one of the most widely used water-soluble polymers.
