  • What is the pH range of polyacrylamide?
  • In the pH range of 3 to 9, it can maintain a good degree of stability; at high pH, the viscosity will be increased gradually. Miscibility: in generally used concentration, polyacrylamide has miscibility with most water-soluble natural or synthetic resins, latex systems, and most of the salts.
  • Is polyacrylamide soluble in water?
  • Polyacrylamide is insoluble in benzene, toluene, xylene, gasoline, kerosene, diesel fuel, but soluble in water. Polyacrylamide can react with alkaline with partial hydrolysis of polyacrylamide. It will have imidization reaction in strongly acidic (pH≤2.5) which will reduce its solubility in water.
  • How to prepare polyacrylamide aqueous solution?
  • Preparation: the polymerization of acrylamide aqueous solution is a common method for preparing polyacrylamide. According to the trigger mode, there are different methods such as thermal initiator and oxidation-reduction induction. Polymer prepared by persulfate thermal initiating has relative small molecular weight at about 20 to about 1,000,000.
  • Is polyacrylamide a strong oxidizing agent?
  • Stable. Incompatible with strong oxidizing agents, aluminium, copper, iron, iron salts 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.
