Description

Bis[[2-(Acryloyloxy)Ethyl]Dimethylammonium] Sulphate is a high-purity, quaternary ammonium salt monomer featuring two polymerizable acrylate groups. This compound is a critical building block for the synthesis of specialty polymers, valued for its ability to impart permanent cationic charge and cross-linking functionality. It is essential for manufacturers in the water treatment, personal care, and advanced materials sectors seeking to develop high-performance flocculants, conditioning agents, and ion-exchange resins.

Application

• Water Treatment Polymers: A key monomer for synthesizing cationic polyacrylamides 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 conditioning polymers for hair care products (conditioners, shampoos) and skin care formulations to enhance softness and manageability.
• Textile & Fabric Treatment: Serves as a monomer for creating durable fabric softeners, antistatic agents, and dye-fixing agents for the textile industry.
• Enhanced Oil Recovery (EOR): Employed in the synthesis of polymers that modify the viscosity of injection water to improve oil displacement in reservoir formations.
• Ion-Exchange Resins & Membranes: A precursor for manufacturing specialty resins and membranes with high ion-exchange capacity for water purification and selective separation processes.
• Adhesives & Coatings: Imparts cationic character and cross-linking sites in formulations for pressure-sensitive adhesives, paints, and industrial coatings to improve adhesion and film properties.
