• Description: Divinylbenzene (DVB) is an organic compound composed of two vinyl groups attached to a benzene ring. Its chemical formula is C10H10. It has a structure where two vinyl (-CH=CH2) groups are attached to adjacent carbon atoms on a benzene ring. Divinylbenzene is categorized as a vinyl aromatic compound and is commonly used as a crosslinking agent in polymer chemistry.
• Uses and Mechanism of Action: Divinylbenzene is widely used as a crosslinking agent in the production of polymers, ceramics, and composites. It is also employed in fields such as materials science, electronics, and membrane technology. In polymer chemistry, divinylbenzene acts as a crosslinking agent, forming covalent bonds between polymer chains and increasing the structural integrity and stability of the resulting materials. In ceramics, it can act as a carbon source, contributing to the formation of carbon-rich phases and enhancing electrical conductivity.
• History and Development: Divinylbenzene has been used in polymer chemistry since the mid-20th century as a crosslinking agent. Its versatile applications and role in improving material properties have led to continued research and development in various fields.
• Production Methods: Divinylbenzene can be synthesized from the reaction of ethylene with benzene in the presence of a catalyst, typically aluminum chloride or aluminum bromide.
