Description

Tetra(Ethylene Glycol) Divinyl is a specialized difunctional monomer featuring terminal vinyl groups connected by a tetraethylene glycol spacer. This molecular structure makes it a valuable crosslinking agent and a versatile building block for creating polymers with tailored properties. It is primarily utilized in the synthesis of hydrogels, specialty resins, and functionalized materials for advanced applications. Industries such as pharmaceuticals, polymer chemistry, and materials science rely on this compound for its reactivity and ability to introduce polyethylene glycol (PEG) chains into networks.

Application

• Crosslinking Agent for Hydrogels: Used in the synthesis of biocompatible and swellable polymer networks for medical and pharmaceutical applications.
• Polymer Modification: Serves as a difunctional monomer to introduce PEG spacers and vinyl functionality into copolymers, affecting flexibility and hydrophilicity.
• Surface Functionalization: Employed to graft reactive vinyl groups onto various substrates for further chemical modification.
• Dendrimer and Macromonomer Synthesis: Acts as a key building block in the controlled construction of dendritic structures and star polymers.
• Photocurable Resins: Incorporated into formulations for UV-curable coatings, inks, and adhesives where PEG chains are desirable.
• Bioconjugation Linker: Provides a PEG-based spacer arm in the development of drug conjugates and diagnostic reagents.
