Poly(ethylene glycol) divinyl ether
Poly(ethylene glycol) divinyl ether (CAS: 50856-26-3) is a homobifunctional crosslinker with the linear formula H₂C=CH(OCH₂CH₂)nOCH=CH₂ and an average molecular weight of Mn 250. This vinyl ether functionalised polyethylene glycol exhibits a density of 1.018 g/mL at 25 °C and a refractive index of n20/D 1.457. It is primarily utilised in polymer science and materials science for the synthesis of novel polymeric architectures and crosslinked networks.
Polymer Synthesis
Serves as a versatile monomer or crosslinker in the synthesis of various polymers, including hydrogels and functional resins. Its divinyl ether functionality allows for controlled polymerisation and network formation.
Materials Science
Enables the development of advanced materials by facilitating the creation of crosslinked polymer networks with tailored properties. Useful in the design of coatings, adhesives, and functional surfaces.
Surface Modification
Can be employed to modify surfaces, imparting specific characteristics such as hydrophilicity or reactivity. This is achieved through covalent attachment via its terminal vinyl ether groups.
