Description

Methacryloyl Oxyethyl Trimethyl Ammonium p-Toluenesulfonate CAS NO 40820-77-7 is a specialized quaternary ammonium methacrylate salt, widely recognized as a cationic monomer. This compound is essential for introducing a permanent positive charge into polymer chains, significantly enhancing their affinity for negatively charged surfaces. It is a critical raw material for manufacturers in the water treatment, personal care, and advanced materials sectors seeking to develop high-performance cationic polymers with superior adhesion, flocculation, or antimicrobial properties.

Application

• Water Treatment Chemicals: Key monomer for synthesizing cationic polyelectrolytes and flocculants used in sludge dewatering, clarification, and wastewater treatment.
• Personal Care & Cosmetics: Used in the production of cationic conditioning polymers for hair care products (shampoos, conditioners) and skin care formulations to improve manageability and feel.
• Paper & Pulp Industry: Manufacture of wet-strength resins, retention aids, and drainage aids to improve paper quality and production efficiency.
• Textile Auxiliaries: Synthesis of cationic dye-fixing agents, softeners, and antistatic agents for fabrics.
• Enhanced Oil Recovery (EOR): Component in polymers designed for viscosity modification and improved oil displacement in reservoir flooding.
• Adhesives & Coatings: Imparts cationic functionality to acrylic adhesives, paints, and primers for improved adhesion to diverse substrates.
• Biomedical Materials: Research applications in creating cationic hydrogels, drug delivery systems, and antimicrobial surface coatings.
