Diethylene glycol divinyl ether (DEGDVE) serves as a versatile chemical due to its ability to easily undergo polymerization, making it a valuable raw material and intermediate in various industries including organic synthesis, pharmaceuticals, agrochemicals, and dyestuffs. Its key purpose is to act as a cross-linking agent in the production of functional materials, such as hydrogels, due to its ability to copolymerize and form diverse structures. These hydrogels, characterized by their high water content and insolubility, find applications in biomedical fields such as drug delivery systems, biosensors, and wound dressings. Furthermore, DEGDVE is used in creating a plugging agent with high-temperature and salt resistance, beneficial for oil extraction by mitigating water production in wells, thereby enhancing oil recovery rates. Additionally, cross-linking copolymerization with DEGDVE can produce unique three-dimensional substances that serve as modified substrate materials, expanding its utility in specialized chemical processes like ethynylation and vinylation.
