Divinylbenzene CAS#1321-74-0

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.

Product Application of Divinylbenzene CAS#1321-74-0

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.
