Description

Methacrylicacid,Sulphopropylester CAS NO 54276-35-6 is a specialized methacrylate monomer featuring a sulfopropyl ester group, which imparts unique ionic and hydrophilic properties. This functional monomer is critical for synthesizing advanced polymers with enhanced water solubility, adhesion, and ionic conductivity. It is primarily sought by R&D chemists and production engineers in the coatings, adhesives, ion-exchange resins, and specialty polymer sectors to develop next-generation materials.

Application

• Ion-Exchange Resins & Membranes: A key monomer for producing cation-exchange resins and membranes used in water purification, desalination, and chromatographic separation.
• Hydrophilic Coatings & Adhesives: Imparts permanent hydrophilicity and adhesion to surfaces in pressure-sensitive adhesives, marine antifouling paints, and biocompatible coatings.
• Superabsorbent Polymers (SAPs): Used in the formulation of high-performance SAPs for hygiene products and agricultural water retention.
• Dispersants & Emulsifiers: Serves as a reactive surfactant or comonomer in emulsion polymerization for stable latex and dispersion production.
• Photoresist & Electronic Chemicals: Employed in the synthesis of photoresist polymers for semiconductor manufacturing due to its reactive double bond and ionic group.
• Drug Delivery Systems: Utilized in creating pH-sensitive or mucoadhesive polymer carriers for controlled pharmaceutical release.

Quality Control

Every batch of Methacrylicacid,Sulphopropylester is produced and tested under a strict quality management system. We ensure the product meets high-purity standards suitable for sensitive polymerization processes. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is kept sealed to prevent absorption of atmospheric moisture, which can affect purity and reactivity.
