Used primarily in the synthesis of cationic polymers for water treatment processes, this chemical aids in the flocculation and removal of negatively charged impurities and organic matter from wastewater. It is a key monomer in producing polyelectrolytes used in municipal and industrial water purification systems. Commonly employed in the paper industry to improve dry strength and retention during papermaking by enhancing fiber bonding. Applied in the formulation of antimicrobial coatings and surfaces due to the biocidal properties of quaternary ammonium groups, making it suitable for use in medical devices, textiles, and hygiene products. Also utilized in the development of contact lens materials and other biomedical applications where controlled hydrophilicity and ionic interaction are required. Its reactive methacrylate group allows for easy copolymerization with other vinyl monomers, enabling tailored polymer design for specific industrial and pharmaceutical applications.
