  • 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 is cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamides (CPAMs) are widely utilized due to their excellent performance in flocculation and sludge dewatering [ 2 ]. Numerous studies have been conducted on CPAM synthesis technologies, including grafting, free radical polymerization, and polymer modification [ 3 ].
  • 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.
  • How can cationic polyacrylamide improve fiber combination?
  • Studies have shown that using chemical agents is a good technique (Chen et al. 1998). Adding a polyelectrolyte, such as cationic polyacrylamide, to improve fiber combination is a promising technique (Hubbe 2006). Polyacrylamide is widely used in various fields because of its molecular structure characteristics and its many varieties.
