Description of mixedisomers

• Divinylbenzene (DVB) consists of a benzene ring bonded to two vinyl groups. It is related to styrene (vinylbenzene) by the addition of a second vinyl group. It is a colorless liquid is 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.

What is Divinylbenzene ?

• With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Divinylbenzene   which has developed particularly rapidly in recent years. Do you know about Divinylbenzene?
• The official answer：Divinylbenzene is a very useful cross-linking agent and is widely used in ion exchange resins, ion exchange membranes, ABS resins, polystyrene resins, unsaturated polyester resins, synthetic rubber, and other fields. However, divinylbenzene is extremely reactive and is very susceptible to free radical polymerization during the distillation process due to metal ions and heat initiation, and the higher the temperature, the faster its polymerization rate. In order to try to avoid the material consumption caused by polymerization, various polymerization inhibitors are often added to prevent free radical polymerization.

What’s the application of Divinylbenzene ?

• Organic synthesis. Divinylbenzene has two ethylenes and when copolymerized produces a three-dimensional structure of insoluble and non-fusible polymers. It is, therefore, a very useful cross-linking agent and is widely used in ion exchange resins; ion exchange membranes; ABS resins; polystyrene resins; unsaturated polyester resins; synthetic rubber; wood processing; carbon processing, etc.
