Description

Tri(Ethylene Glycol) Methyl Vinyl Ether, 98 is a high-purity, reactive ether monomer featuring both a vinyl group and a triethylene glycol chain. This unique bifunctional structure makes it a valuable building block for synthesizing specialty polymers and functional materials with tailored properties. It is essential for manufacturers in the polymer, coatings, and advanced materials sectors seeking to introduce hydrophilic, crosslinkable, or reactive sites into their products.

Application

• Reactive Diluent & Monomer: Used in UV-curable coatings, inks, and adhesives to modify viscosity and enhance crosslinking density.
• Polymer Modification: Serves as a comonomer for producing hydrophilic or functionalized polyethers, polyesters, and acrylics.
• Crosslinking Agent: Imparts crosslinkable vinyl groups into polymer backbones for improved thermal and chemical resistance.
• Surface Active Agents: A precursor for synthesizing non-ionic surfactants and emulsifiers with ethylene oxide units.
• Pharmaceutical Intermediates: Employed in the synthesis of prodrugs and polymer-drug conjugates due to its PEG-like spacer and reactive termini.
• Specialty Resins: A key ingredient in formulating advanced epoxy and vinyl ester resins for composite materials.
