  • What is poly acrylamide used for?
  • We are working to minimize these delays as quickly as possible. Poly (acrylamide) is a water-soluble polymer made up of acrylamide subunits. Polyacrylamides have been reported to be protein resistant and biocompatible. Polyacrylamides have been used as carriers for delivery of drugs and bioactive compounds, or to as tissue engineering materials.
  • 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.
  • What is anionic polyacrylamide used for?
  • Anionic polyacrylamide can be used as a cytoplasm additive in the paper industry with better retention and drainage effect. It has a particularly dispersing effect for long-fiber pulp when its molecular weight is greater than 3.5 million. In addition, it can also be used as a water treatment agent.
  • 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.
