  • Applications

    2-(Trimethylammonio)ethyl methacrylate chloride (CAS 5039-78-1) is a methacrylate monomer bearing a quaternary ammonium group, typically used to synthesize cationic polymers. In industry, it is mainly used as a monomer unit to produce cationic polymers for plastics and polymeric materials, and is incorporated into waterborne coating, paint, and ink systems to improve adhesion and interaction with negatively charged substrates. It is also used as a backbone for polymers in cosmetics and personal care to enhance rheology and conditioning properties. In addition, this monomer serves as a monomeric platform for flocculants and retention aids in papermaking and water treatment, helping to improve retention and dispersion of additives. Its applications depend on local regulations and formulation limits.
