Tetraethylene glycol diacrylate (TetEGDA) is a hydrophilic bifunctional acrylate monomer containing two reactive acrylate groups connected through a tetraethylene glycol spacer. It is commonly used as a crosslinking reagent in hydrogel systems, UV-curable polymers, biomaterials research, and polymer network formation.
Synonyms and related names: TetEGDA, tetraethylene glycol diacrylate crosslinker, PEG-based diacrylate monomer, hydrophilic acrylate crosslinker.
The tetraethylene glycol backbone contributes flexibility, hydrophilicity, and water compatibility, making TetEGDA useful for preparing soft crosslinked polymer systems and hydrogel materials used in biomedical and materials research applications.
Researchers working with PEG-based acrylate crosslinkers may also be interested in other PEG diacrylate and multifunctional acrylate systems for hydrogel preparation and photopolymerization studies.
