Description

Potassium 2-(3-Sulphonatopropoxy)Ethyl Acrylate is a specialized, water-soluble anionic monomer featuring a polymerizable acrylate group and a sulfonate functionality. This unique structure is engineered to impart permanent ionic character, hydrophilicity, and enhanced adhesion properties to polymer chains. It is a critical raw material for formulators and polymer chemists seeking to develop advanced materials with superior performance in aqueous systems. Key industrial applications include the production of high-performance dispersants, superabsorbent polymers, and coatings that require excellent stability and compatibility.

Application

• Dispersants & Superplasticizers: A key monomer for synthesizing polycarboxylate ether (PCE)-based superplasticizers and pigment dispersants in the construction and coatings industries.
• Superabsorbent Polymers (SAPs): Used to introduce sulfonate groups into acrylic acid-based SAPs for personal care and agricultural products, improving absorption rate and salt tolerance.
• Water Treatment Chemicals: Incorporated into scale and corrosion inhibitor polymers for industrial cooling water and boiler water systems.
• Textile & Leather Auxiliaries: Serves as a co-monomer in polymers used as dyeing assistants, finishing agents, and tanning auxiliaries.
• Adhesives & Sealants: Enhances the water resistance, adhesion, and rheological properties of acrylic-based pressure-sensitive adhesives and sealants.
• Enhanced Oil Recovery (EOR): A component in polymers designed for mobility control and conformance improvement in oilfield applications.
• Photoresist & Electronic Materials: Used in the formulation of radiation-sensitive polymers for photoresists in semiconductor manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or hydrolysis. Keep away from heat sources and incompatible materials such as strong oxidizing agents.
