Description

Poly(Oxy-1,2-Ethandiyl), α-(2-Methyl-1-Oxo-2-Propenyl)-ω-(Isotridecyloxy), Mittlerer Eo 20 Mol is a specialized reactive surfactant and macromonomer, designed to impart unique surface-active and polymerizable properties. Its value lies in its ability to act as a functional building block, enabling the creation of polymers with tailored hydrophilicity, adhesion, and compatibility. This product is essential for formulators and polymer chemists in industries such as advanced coatings, adhesives, and specialty polymer synthesis, where precise control over material properties is required.

Application

• Macromonomer for Graft Copolymers: Used as a reactive surfactant to synthesize comb-like or graft copolymers with controlled architecture.
• Surface Modifier in Coatings: Enhances adhesion, wetting, and dispersion stability in water-based and solvent-based coating formulations.
• Stabilizer in Emulsion Polymerization: Acts as a reactive emulsifier or stabilizer in the production of acrylic, styrene-acrylic, and vinyl acetate copolymers.
• Additive for Adhesives & Sealants: Improves compatibility and performance in pressure-sensitive adhesives (PSAs) and construction sealants.
• Intermediate for Specialty Polymers: Serves as a key intermediate for creating polymers with specific hydrophilic-lipophilic balance (HLB) for personal care or agrochemical applications.
• Textile & Fiber Treatment: Used in fiber sizing and finishing to improve processability and final fabric properties.

Quality Control

Our production of this macromonomer adheres to strict quality protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as degree of ethoxylation, methacrylate content, and residual monomers are monitored. Certificates of Analysis (COA) detailing purity, assay, and physical specifications are provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent moisture absorption and potential premature polymerization. Keep away from heat and incompatible materials such as strong oxidizing agents and initiators.
