Application
Divinylbenzene, a 50% mixture of isomers, is a versatile liquid primarily used for its reactive properties. It serves as a crosslinking agent in the production of polyester resins and the synthesis of highly crosslinked macroporous styrene. Additionally, it acts as an intermediate in the creation of ion exchange resins and is instrumental in manufacturing rubber, aiding petroleum production, and developing polymeric core-shell nanoparticles. Furthermore, it is utilized in the synthesis of monodispersed poly divinylbenzene microspheres. Although slightly less dense than water and insoluble in it, the vapors can be toxic, and its flash point is below 141°F. The product is predominantly composed of m-isomers but includes o- and p-isomers as well. Due to its potential to polymerize, it often contains an inhibitor to prevent this reaction. Divinylbenzene is typically represented by its molecular weight of 130.20, with a specific gravity of 0.93, and exhibits a boiling point between 195-200℃. As a commercial product, it is identified by its CAS number on most regulatory lists, emphasizing its prevalent use across various industrial applications.
