Used primarily as a cationic monomer in the synthesis of water-soluble polymers for flocculation and coagulation processes. Commonly applied in water and wastewater treatment to remove suspended solids, oils, and organic matter due to its positive charge, which neutralizes negatively charged particles. Also utilized in the paper industry to improve retention and drainage during papermaking. Found in enhanced oil recovery operations as a component of polymer flooding systems to improve oil displacement. Employed in personal care products such as conditioners and hair fixatives for its antistatic and film-forming properties. Additionally, used in textile and leather processing to improve dye fixation and fabric softness.
