Description

Poly(Ethylene Glycol) Ethyl Ether Methacrylate is a versatile methacrylate monomer functionalized with a hydrophilic poly(ethylene glycol) ethyl ether chain. This unique structure provides a valuable combination of polymerizable methacrylate functionality with water-solubility and chain flexibility, making it a critical building block for advanced polymeric materials. It is essential for formulators and polymer chemists in industries such as specialty coatings, biomedical hydrogels, and personal care, where tunable hydrophilicity and reactive sites are required.

Application

• Hydrogel Synthesis for Biomedical Devices: A key monomer for creating biocompatible, water-swollen networks used in contact lenses, wound dressings, and drug delivery systems.
• UV-Curable Coatings and Inks: Imparts flexibility, adhesion, and moisture resistance in coatings for electronics, overprint varnishes, and 3D printing resins.
• Surface Modification and Grafting: Used to create hydrophilic polymer brushes on surfaces (e.g., medical devices, membranes, sensors) to reduce fouling and improve biocompatibility.
• Dispersants and Stabilizers: Serves as a macromonomer in the synthesis of comb-like copolymers that act as effective dispersants for pigments and nanoparticles.
• Personal Care Polymers: Incorporated into hair fixatives, skincare films, and cosmetic formulations to enhance feel, moisture retention, and film-forming properties.
• Adhesives and Sealants: Modifies the properties of acrylic adhesives, improving their tack, flexibility, and compatibility with various substrates.

Quality Control

Our Poly(Ethylene Glycol) Ethyl Ether Methacrylate is produced under a stringent quality management system. Each batch is analyzed to ensure consistent purity, functionality, and performance. Key parameters monitored include assay (methacrylate content), degree of ethoxylation, color, acid value, and water content. Certificates of Analysis (COA) detailing all test results are provided with every shipment to support your quality assurance and regulatory compliance needs.

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). To maintain optimal quality and prevent polymerization, it is recommended to store under an inert atmosphere (e.g., nitrogen) and to use an appropriate inhibitor as supplied. Keep away from heat, sparks, and open flame.
