• Description: Divinylbenzene is a clear yellow liquid with an aromatic odour. It is a highly flammable and reactive chemical, and the liquid and vapour are combustible. It is incompatible with strong acids and oxidising agents and peroxides. Divinylbenzene reacts vigorously with strong oxidising agents. It also reacts exothermically with both acids and bases, with reducing agents (such as alkali metals and hydrides), and release gaseous hydrogen. May react exothermically with both acids and bases or initiators undergo exothermic polymerisation. It is an extremely versatile chemical cross-linking agent used to improve polymer properties. Divinylbenzene has extensive industrial applications for example, in the manufacture of adhesives, plastics, elastomers, ceramics, biological materials, catalysts, membranes, pharmaceuticals, specialty polymers, and ion exchange resins, as coatings, divinyl benzene has been reported to improve surface properties of rubber goods for biomedical applications, used in photocurable protective coatings for wood, metal, glass, and plastic materials.
• Physical properties: Divinylbenzene is a water-white to straw colored liquid. Slightly less dense than water and insoluble in water. Vapors may be toxic. Used in making rubber.Synthetic rubber is any one of a group of man-made elastomers that approximate one or more of the properties of natural rubber(polyisoprene). Divinylbenzene has been used in Styrene-Butadiene copolymers (SBR) as adhesives and as processing aids in the extrusion of general purpose rubbers. Rubbers used as impact modifiers such as Methacrylate-Butadiene-Styrene (MBS) have been improved with the inclusion of Divinylbenzene.
• Uses: Divinylbenzene (DVB) is an extremelyversatile cross-linking agent that also improves polymer properties. it has been used to manufacture adhesives,plastics, elastomers, ceramics, biologicalmaterials, coatings, catalysts, membranes, pharmaceuticals, specialty polymers, and ion exchange resins. DVB has been found to improve the hightemperature strength of adhesives used tobond aluminum to aluminum. Used in anacrylic hydrosol to bond Bakelite resin andpolyester film, DVB was found to increasecreep rupture time dramatically. DVB hasfound utility in cross-linked styrene/butadienepolymers used for caulks and mastics for theconstruction industry. DVB has been used in the production ofreversed-phase packings for liquidchromatography. Highly cross-linkedpolystyrene packings have been shown tofunction under extreme conditions of highpressures and temperatures. Ion exchangechromatography (IEC) is applicable to theseparation of almost any type of chargedmolecule, from large proteins to smallnucleotides and amino acids. Divinylbenzene is a specialty monomer used primarily to make cross-linked polystyrene resins. The largest use of divinylbenzene (DVB) [CAS: 1321-74-0] is in ion-exchange resins for domestic and industrial water softening. Ion-exchange resins are also used as solid acid catalysts for certain reactions, such as esterification. Divinylbenzene is manufactured by dehydrogenation of diethylbenzene, which is an internal product in the alkylation plant for ethylbenzene production. Comonomer for preparation of crosslinked polymers in production of ion exchange beads and gel permeation chromatography polystyrene beads; polymerization monomer for synthetic rubber, drying oils, and casting resins Divinylbenzene is used as a reactive monomer in polyester resins and for the synthesis of highly crosslinked macroporous styrene as well as a crosslinking agent. It acts as an intermediate in the production of ion exchange resin. Further, it is used in making rubber, petroleum production and polymeric core shell nanoparticles. In addition, it is used to synthesize monodispersed poly divinylbenzene microspheres.
