Application
Divinylbenzene, 55% Mixture of Isomers, is a versatile chemical used across various industries. Its primary purpose lies in its role as a reactive monomer in polyester resins and in the synthesis of highly crosslinked macroporous styrene. This compound serves as a key crosslinking agent and an intermediate in the production of ion exchange resins. It is also utilized in the manufacturing of rubber, advancements in petroleum production, and the development of polymeric core-shell nanoparticles. Additionally, divinylbenzene is instrumental in creating monodispersed polydivinylbenzene microspheres. Commercially, this product comprises a mixture of ortho, meta, and para isomers, with the meta-isomer being predominant, and typically includes a stabilizing inhibitor to prevent unwanted polymerization. While this pale, straw-colored liquid is characterized by its low density and insolubility in water, its stability and reactivity make it an essential component in numerous applications.
