Description

Allyloxypolyethyleneglycol CAS NO 27274-31-3 is a reactive polyether monomer featuring a terminal allyl ether group and a hydrophilic polyethylene glycol chain. This unique bifunctional structure makes it a versatile intermediate for introducing hydrophilic, flexible spacer arms into polymers and surfaces. It is primarily utilized in the synthesis of specialty polymers, functional coatings, and advanced materials where controlled crosslinking and surface modification are required. Key industries that rely on this chemical include polymer manufacturing, specialty adhesives, and biomedical material research.

Application

• Reactive Monomer for Hydrophilic Polymers: Used in the synthesis of crosslinked hydrogels, polyurethane dispersions (PUDs), and other polymers requiring water solubility or swellability.
• Surface Modifying Agent: Imparts hydrophilic properties to surfaces for applications in coatings, textiles, and medical devices to improve biocompatibility or anti-fog properties.
• Macromonomer for Graft Copolymers: Serves as a building block for creating comb-like or graft copolymers with tailored properties for use as dispersants, thickeners, or compatibilizers.
• Crosslinker in UV-Curable Systems: Functions as a reactive diluent or crosslinking agent in UV-curable inks, coatings, and adhesives, contributing to flexibility and adhesion.
• Intermediate for Functional Silicones: Used to modify silicones with polyether chains, creating surfactants, foam stabilizers, or personal care ingredients.
• Bioconjugation and Drug Delivery: Employed in research for PEGylation strategies, creating linkers for attaching drugs, proteins, or targeting moieties in pharmaceutical development.

Quality Control

Our Allyloxypolyethyleneglycol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, functionality, and performance. Key parameters monitored include hydroxyl value, allyl ether content, molecular weight distribution (by GPC), and water content. Certificates of Analysis (COA) documenting these specifications are available for every shipment upon request, providing full traceability and compliance data for your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture uptake and potential oxidation. Keep away from strong oxidizers and heat sources.
