DESCRIPTION
General description
Divinylbenzene (DVB) consists of a combination of meta and para isomers of DVB and ethylvinylbenzene. It can be used as a monomer for the preparation of linear polydivinylbenzene by anionic polymerization.[1][2] Divinylbenzene (DVB) is a bis unsaturated monomer. DVB along with styrene as a co monomer is used in producing cross linked polymers. Several examples have reported. Polymerization with high concentrations of DVB produces popcorn polymers.
Application
DVB can be co-polymerized with sulfur due to its high reactivity. It can be used as a cathode material in lithium-sulfur batteries.[3] It can also be used as a cross-linker that increases the rigidity and reduces the template leakage of the molecular imprinted polymers (MIPs).[4] DVB can be polymerized to form poly(divinylbenzene) that can be carbonized to fabricate activated carbon monoliths.[5] DVB is used in polymeric core shell nanoparticles[6] and as a crosslinking agent.[7] DVB may be used as a monomer for the synthesis of highly crosslinked macroporous styrene/DVB polymers.[8] It may also be used to synthesize monodispersed poly-DVB microspheres.[9]
