Divinylbenzene Properties

Molecule Structure Image



Divinylbenzene consists of a benzene ring bonded to two vinyl groups. It is related to styrene (vinylbenzene) by the addition of a second vinyl group. Divinylbenzene, as it is usually encountered, is a 2:1 mixture of m- and p-divinylbenzene, containing also the corresponding ethylvinylbenzene isomers. It is manufactured by the thermal dehydrogenation of isomeric diethylbenzenes. When reacted together with styrene, divinylbenzene can be used as a reactive monomer in polyester resins. Styrene and divinylbenzene react together to form the copolymer styrene-divinylbenzene, S-DVB or Sty-DVB. The resulting cross-linked polymer is mainly used for the production of ion exchange resin.
