  • What is a net cationic polyacrylamide dry strength agent?
  • Guangyan Wang and Yi Jing* A new net-cationic polyacrylamide dry strength agent was synthesized through free radical polymerization using acrylamide (AM), itaconic acid (IA), N,N-dimethylacrylamide (F), and sodium methallyl sulfonate (T).
  • What are the advantages of cationic polyacrylamide?
  • Cationic polyacrylamide in particular has an advantage in that it has a positive charge, which makes the addition of a precipitation agent such as aluminum sulfate unnecessary when used in the production of paper.
  • Does polymer distribution affect mechanical properties of cationic polyacrylamide dry-strength resin?
  • Mihara and Yamauchi showed the effect of polymer distribution on mechanical properties of paper sheets containing various amounts of cationic polyacrylamide dry-strength resin by DMA analysis performed in the 100–300 °C temperatures range in vibration mode at various frequencies [ 100 ].
  • What is an anionic polyacrylamide used for?
  • There is a wide range of uses for anionic polyacrylamides and these include wastewater treatments aids, retention aids, and strength agents in papermaking, hydraulic stimulation, and enhanced oil recovery in oil field applications, mineral processing, and as soil conditioners in agricultural uses.
