Divinylbenzene (DVB) is an organic compound with the chemical formulaC6H4(CH=CH2)2 and structureH2C=CH−C6H4−HC=CH2 (a benzene ring with two vinyl groups as substituents). It is related to styrene (vinylbenzene, C6H5−CH=CH2) by the addition of a second vinyl group. 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.
