General description
Divinylbenzene (DVB) has a benzene ring in combination with meta and para isomers of DVB and ethylvinylbenzene. It acts as a monomeric unit which facilitates the preparation of polydivinylbenzene by anionic polymerization.
Application
DVB can be used as a crosslinking agent in the synthesis of silicon/carbon composite for use as an anode material for lithium ion batteries. It can also be used as a monomer to synthesize dimer particles by seed polymerization method for potential uses in electrical clutches and shock absorbers.
Other Notes
contains 4-ethylvinylbenzene and 3-ethylvinylbenzene
