Divinylbenzene (DVB) is an organic compound with the chemical formula {{chem2|C6H4(CH\dCH2)2}} and structure {{chem2|H2C\dCH\sC6H4\sHC\dCH2}} (a benzene ring with two vinyl groups as substituents). It is related to styrene (vinylbenzene, {{chem2|C6H5\sCH\dCH2}}) by the addition of a second vinyl group.CRC Handbook of Chemistry and Physics 65Th Ed. It is a colorless liquid manufactured by the thermal dehydrogenation of isomeric diethylbenzenes. Under synthesis conditions, o-divinylbenzene converts to naphthalene and thus is not a component of the usual mixtures of DVB.{{Cite book|title=Denis H. James William M.
