  • Is polyacrylamide toxic to humans?
  • Toxicity: Polyacrylamide itself is non-toxic, but if it contains polymerized monomers (a double bond), it would be toxic to humans. For this reason, upon the completion of its preparation, a certain amount of sodium bicarbonate should be added to remove residual monomers. The above information is edited by the chemicalbook of Dai Xiongfeng.
  • 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.
  • 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 make colloidal polyacrylamide?
  • Colloidal polyacrylamide: add 1 200 kg of deionized water into the hydrolysis reactor, add under stirring of acrylonitrile, 0.3 kg of aluminum hydroxide, cupric hydroxide for complex catalysis, and have hydrolysis reaction at 85~125 °C. After completion of the reaction, distill off the unreacted monomer acrylonitrile.
