Description

Allyloxy(Tetraethylene Oxide), Methyl Ether, Tech-90 is a specialized polyether derivative featuring an allyl ether terminus and a methyl ether cap. This compound matters as a versatile, reactive intermediate for the synthesis of functional polymers and surfactants, offering a balance of hydrophilicity and cross-linking capability. It is needed by formulators and researchers in the polymer, coatings, and specialty chemical industries seeking to introduce poly(ethylene glycol) (PEG) spacers with a polymerizable double bond.

Application

• Reactive Monomer for Functional Polymers: Used in the synthesis of cross-linkable PEG-based hydrogels, coatings, and adhesives.
• Surfactant & Emulsifier Intermediate: Serves as a building block for creating non-ionic surfactants with tailored HLB values.
• Pharmaceutical & Bioconjugation Linker: Acts as a hydrophilic, functionalizable spacer arm in drug delivery systems and protein PEGylation.
• Polymer Modification: Employed to introduce hydrophilic PEG chains and reactive sites onto polymer backbones via grafting reactions.
• UV/EB Curable Formulations: Functions as a reactive diluent or cross-linker in radiation-curable inks, resins, and coatings.
• Lubricant & Plasticizer Additive: Imparts lubricity and flexibility as an additive in specialty lubricants and polymer matrices.
