Description

Poly(Ethylene Glycol) Methyl Ether Methacrylate is a reactive methacrylate monomer featuring a hydrophilic poly(ethylene glycol) side chain. This bifunctional structure is critical for imparting permanent hydrophilicity, flexibility, and biocompatibility to polymer matrices. It is an essential building block for formulators and polymer chemists in the biomedical, personal care, and advanced materials sectors seeking to modify surface properties and enhance material performance.

Application

• Hydrogel Synthesis: A key monomer for creating soft, water-swollen hydrogels used in contact lenses, wound dressings, and drug delivery systems.
• Surface Modification & Coatings: Used to create permanent hydrophilic, protein-resistant, or anti-fouling coatings on medical devices, membranes, and sensors.
• Bioconjugation & Drug Carriers: The terminal hydroxyl group on the PEG chain can be functionalized for attaching drugs, peptides, or targeting ligands in pharmaceutical applications.
• UV/EB Curable Systems: Acts as a reactive diluent and modifier in inks, adhesives, and coatings cured by ultraviolet light or electron beams, improving flexibility and adhesion.
• Acrylic Resin Modification: Incorporated into acrylic copolymers to enhance water solubility, reduce viscosity, or improve impact resistance and weatherability.
• Personal Care Polymers: Used in the synthesis of film-forming agents, hair fixatives, and skin-feel enhancers in cosmetic formulations.

Quality Control

Our Poly(Ethylene Glycol) Methyl Ether Methacrylate is manufactured under a strict quality management system. Each batch is analyzed to ensure consistent purity, molecular weight distribution, and low levels of inhibitor and residual monomers. Certificates of Analysis (COA) documenting key parameters such as assay, water content, and color are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at 2-8°C (refrigerated) or as specified on the label to maximize shelf life and inhibit premature polymerization. Keep away from strong bases and incompatible materials. Always refer to the Safety Data Sheet (SDS) for complete handling and storage instructions.
