Description

2-Propenoic Acid, 3-(3-Sulfophenyl)-, 1-Methyl Ester, Sodium Salt (1:1), (2E)- is a specialized anionic monomer featuring a sulfonated aromatic ring and an acrylate ester functionality. This unique structure makes it a valuable building block for synthesizing advanced polymers with enhanced hydrophilicity, ionic character, and thermal stability. It is primarily sought by R&D chemists and production engineers in the polymer and specialty chemical industries for creating high-performance dispersants, superplasticizers, and functional materials.

Application

• Polymer Synthesis: Key monomer for producing sulfonated polyelectrolytes and ion-exchange resins.
• Dispersants & Superplasticizers: Imparts superior water-reducing and dispersing properties in concrete admixtures and pigment suspensions.
• Water Treatment Chemicals: Used in the formulation of scale inhibitors and antiscalants for industrial water systems.
• Enhanced Oil Recovery (EOR): Component in polymers designed to modify viscosity and improve oil displacement in reservoir flooding.
• Textile & Leather Auxiliaries: Serves as a co-monomer in binders and finishing agents to improve dyeability and fastness.
• Paper Chemicals: Used in the manufacture of wet-strength resins and retention aids.
• Personal Care & Cosmetics: Potential use in hair fixative polymers and thickeners for its film-forming and anionic properties.
