Description

(Ar-Vinylbenzyl)Trimethylammonium Chloride is a versatile quaternary ammonium salt monomer featuring a reactive vinylbenzyl group. This compound is a critical building block for synthesizing specialty polymers with permanent cationic charges, which are essential for applications requiring strong ionic interactions. It is primarily sought by manufacturers in the water treatment, biotechnology, and advanced materials sectors for creating ion-exchange resins, flocculants, and functional polymeric materials.

Application

• Ion-Exchange Resins: A key monomer for producing strong anion-exchange resins used in water purification, demineralization, and chromatography.
• Polyelectrolytes & Flocculants: Used in the synthesis of cationic polyelectrolytes for wastewater treatment, sludge dewatering, and papermaking processes.
• Functional Polymer Coatings: Incorporated into coatings and films to impart antimicrobial properties or modify surface charge for improved adhesion.
• Biotechnology Supports: Serves as a precursor for functionalizing surfaces of beads and membranes used in protein purification, enzyme immobilization, and diagnostic assays.
• Enhanced Oil Recovery (EOR): Used in formulating polymers that alter the rheology of injection water to improve oil displacement in reservoirs.
• Dyeing & Textile Auxiliaries: Employed in the synthesis of polymers that act as dye-fixing agents or antistatic coatings for textiles.
