Description

(Carboxymethyl)[2-(Methacryloyloxy)Ethyl]Dimethylammonium Chloride, Sodium Salt is a specialty quaternary ammonium monomer featuring both a polymerizable methacrylate group and a carboxymethyl functionality. This unique structure makes it a highly versatile building block for synthesizing advanced polymers with permanent cationic charge and enhanced water solubility. It is essential for manufacturers seeking to develop high-performance flocculants, dispersants, and functional materials in water treatment, paper production, and personal care formulations.

Application

• Water Treatment Chemicals: Key monomer for producing cationic polyelectrolytes used as flocculants and coagulants in municipal and industrial wastewater treatment.
• Paper Industry Additives: Used in the synthesis of retention aids, drainage aids, and strength resins to improve paper quality and manufacturing efficiency.
• Enhanced Oil Recovery (EOR): Serves as a monomer for polymers that modify the viscosity and flow properties of injection fluids.
• Personal Care & Cosmetics: Building block for conditioning polymers in shampoos, hair gels, and skincare products, providing antistatic and film-forming properties.
• Textile Auxiliaries: Used in the production of dye-fixing agents, softeners, and antistatic finishes for synthetic and natural fibers.
• Dispersants & Stabilizers: For pigments, ceramics, and cement to improve dispersion stability and processing.
• Ion-Exchange Resins & Membranes: A functional monomer for creating membranes with specific ion-selectivity for separation processes.
• Biomedical Materials: Investigated for use in drug delivery systems and non-fouling surface coatings due to its zwitterionic potential.
