Description

Bis[n-[3-(Dimethylamino)Propyl]Methacrylamide] Sulphate is a specialized quaternary ammonium salt monomer with a unique bifunctional structure. This compound is valued for its ability to introduce permanent cationic charge and polymerizable methacrylamide groups into synthetic polymers. It is primarily sought by R&D chemists and formulators in the water treatment, personal care, and specialty coatings industries for creating high-performance flocculants, conditioning agents, and antimicrobial polymers.

Application

• Water Treatment Chemicals: A key monomer for synthesizing cationic polyacrylamides (CPAM) and other flocculants used in municipal and industrial wastewater clarification, sludge dewatering, and papermaking retention aids.
• Personal Care & Cosmetics: Used in the production of cationic polymers for hair conditioners, skin creams, and other formulations where substantive film-forming and conditioning properties are required.
• Specialty Coatings & Adhesives: Imparts cationic functionality and cross-linking sites in coatings for textiles, paper, and other substrates to improve adhesion, dye affinity, and water resistance.
• Antimicrobial Polymers: Serves as a building block for creating polymers with inherent biocidal properties for applications in hygiene products and surface treatments.
• Enhanced Oil Recovery (EOR): A potential component in synthesizing polymers used for mobility control and profile modification in oilfield applications.
• Dyeing & Textile Auxiliaries: Used to manufacture cationic agents that improve dye uptake and fastness on synthetic fibers like polyacrylonitrile.
