Description

α-(2-Methyl-1-Oxo-2-Propenyl)-ω-(Sulfooxy)Poly[Oxy(Methyl-1,2-Ethanediyl)], Sodium Salt is a specialized reactive polymer surfactant, characterized by its terminal sulfonate and methacrylate groups. This unique structure provides excellent wetting, dispersing, and emulsifying properties, making it a critical component in advanced material synthesis. It is primarily used by formulators in the coatings, adhesives, and advanced polymer industries seeking to enhance product performance and stability.

Application

• As a reactive surfactant and emulsifier in the emulsion polymerization of acrylics, styrene-acrylics, and vinyl acetate polymers.
• As a dispersing and stabilizing agent in the formulation of high-performance water-based paints, coatings, and inks.
• As a key functional additive in the production of pressure-sensitive adhesives (PSAs) and sealants to improve adhesion and cohesion.
• In the synthesis of specialty polymers and copolymers where the polymerizable end-group allows for covalent incorporation into the polymer matrix.
• As a compatibilizer and processing aid in composite materials and polymer blends.
• In industrial and institutional cleaning formulations as a wetting and soil-suspending agent.
